The Post – Odd Goings-On in the Fiddler Tank – Is Scarlett Acting Pregnant Again?

March 16, 2008

When I first I walked by the fiddler tank yesterday morning, I was sleepy and oblivious. Then I did a double-take. Sitting at the front of the tank was the discarded molted shell of somebody. On closer examination, and with my husband’s consultation too, we both agreed it was Melanie Hamilton’s discard. That means she is at the moment most likely to get pregnant if Admiral Byrd invites her in.

At the same time we noticed that Scarlett O’Hara was sitting on top of the water filter….again. The last time she did that, we noticed shortly afterward that she was pregnant.

Admiral Byrd of course, was marching up and down the tank, claw arm held high, and waving.

To continue – Scarlett O’Hara spent the entire day and evening yesterday, on top of the water filter. She is still there this morning. She has never done that before or since, except when she was pregnant. I know she is still alive because she is “blowing bubbles.” Crabs foam sometimes when they’re out of water, to moisten their gills.

Even when I freaked out Admiral Byrd yesterday, and scared Melanie Hamilton out of her live rock because I was cleaning the tank and accidentally bumped the live rock, Scarlett O’Hara didn’t leave the filter perch. She just moved down into the filter for a bit, then climbed back up. Admiral Byrd meanwhile kept trying to climb the heater power cord up to the top of the filter to be near her, but he couldn’t quite do it with that large claw.

Yesterday afternoon we noticed that Melanie Hamilton remained outside the live rock, sitting there on the gravel serenely watching Admiral Byrd flex his claw. Then she spent the rest of the afternoon and evening in his cave lair. This morning she was resting just outside his lair, picking algae off the rock. He was napping inside.

With any luck, we can try the larvae thing again somtime soon?

I am in the middle of re-establishing the nursery tank. I had emptied everything from the original set-up, cleaned out the tank, put down the one inch or so of the calcium-releasing sand, and added the water. Now I did forget to rinse the sand out, so the tank water was cloudy at first, but it has settle out by now. I’m not sure how one effectively rinses sand out anyway without half of it going down the drain. I will say the white sand really makes the inside of the tank bright when the light is on. If we get babies again, it should be much easier to see them in such a bright tank.

I couldn’t decide whether to make the 3 gallons of water I added marine or brackish. I guess I should start brackish because first we’ll have to move the mom, whichever one of them it is, from their tank, which is brackish into this one. I wouldn’t want to shock them. Right now the tank is on the “marine side” of brackish. I’ll adjust the salinity with a bit more water shortly.

The live rock is back in the tank hopefully doing its thing to establish the nitrogen cycle. Both the air filter AND the bubbler are running and so hopefullly the tank environment will establish itself as quickly as possible. Rather than replace the old water filter cartridge and lose whatever nitrogen-fixing bacteria that had started to thrive in it, I left everything in place and returned it to the tank.

An interesting about the old water in that tank. I tested it before I emptied it out just to see if the nitrite levels ever came down. They read zero, and the nitrates were in the “okay” zone. I guess once I stopped using the live phytoplankton and let the water filter run for a few days, that was what it needed. So the phytoplankton was most likely the culprit in the high nitrites. In any event, I dumped the old water and just started with fresh sea/brackish water all over again.

One thing – that Reef Calcium product that I’d hoped would raise the alkalinity but not raise the pH, when added to half strength Instant Ocean… maybe it didn’t raise the pH but it didn’t solve the problem of the pH being too high from the Instant Ocean even when I used that at half strength. So I still had to use a pH lowering solution and this morning it is about 8.0 vs 8.4 that it was yesterday. So that’s perfect . At least though, the Reef Calcium did raise the alkalinity.

I will keep you all posted on any news from the adult tank. Keeping good thoughts for a new crop of larvae babies. Stay tuned.

The Post – Admiral Byrd is Peeking & New Aquarium Products

Some Fiddler Updates – New Product Technical Details and Romance

1) Preparations, Take 2, for the Fiddler Crab Nursery Tank:

I came home from PetsMart yesterday armed with calcium sand to replace the gravel in the nursery aquarium. That project will commence later today. The sand is actually something called Seachem Meridian Tidal Marine Substrate. It’s basically calcium carbonate precipitated from ocean waters by coral. It will stabilize the calcium and alkalinity levels in the water, and keep the pH from getting too low. Its porous structure and size supposedly are good for the growth of denitrifying bacteria. We shall see.

At the very least, it’s a dual purpose as I can also use this sand for the bottom of the land hermit crab cage I just bought. The land hermit crab project will be ramping up soon.

I also picked up some liquid food that should work fine for the larvae. I’d mentioned a product called JBL Nobilfluid that a gentleman from Finland used to raise his crab larvae. However the Nobilfluid is made in Germany and appears to be available in Finland, Germany, England, Italy and the UK, but I couldn’t tell if it was available here in the US. I could get it from a UK website but between the exchange rate and the shipping, I expect the cost is prohibitive. A JBL representative answered my email yesterday and said their product is not available in the US yet.

I found this new product at PetsMart called Kent Marine ZooPlex. The problem I had with the fiddler babies was trying to find liquid plankton to feed them. My mistake was getting live liquid phytoplankton, which made the tank toxic and killed them. I realized larval crabs need zooplankton, which is animal plankton = roughly translated: MEAT. Phytoplankton, being plant based, is the wrong plankton. Larval crabs are carnivores, not vegetarians. Anyway, Kent Marine ZooPlex is “concentrated aquacultured Marine Zooplankton” and is geared toward invertebrates including larvae. The bottle notes it can be used as a brine shrimp replacement. So this sounds like it might be just the thing for liquid feeding of newborn larval crabs who are too small to chase live brine shrimp around.

I will still need to get the dried brine shrimp eggs to hatch when I know I have a pregnant female ready to shed her eggs. The brine shrimp hatchery project will come a bit later.

2) How to raise the alkalinity of the water for the brackish tank without raising the pH?

The dilemma I have when using Instant Ocean to make up the brackish tank water for the adult crabs, is that I have to use it at about half strength. That way I get a salinity of about 1.010 instead of 1.020-1.024. The trouble is, that makes the alkalinity way too low meaning there’s not enough calcium in the water for the crabs when they molt.

I’ve tried adding Seachem’s Marine Buffer, to raise the alkalinity and it’s very successful, but it also raises the pH way up to 8.3. That’s fine for a marine tank, but for the brackish tank, the fiddler crabs seem to like the pH closer to 7.8-8.0 I have a constant battle trying to get the salinity low enough, the alkalinity high enough and the pH “just right” somewhere between a freshwater tank and a marine tank. When I use the Marine Buffer I have to then add something to lower to pH.

I was hoping to find something that would raise the alkalinity, but not the pH when I use Instant Ocean to make up the brackish water. Yesterday I came across Seachem’s Reef Calcium. The website description reads:

Reef Calciumβ„’ is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH.”

I am going to try the Reef Calcium product and see if that solves the problem. I will let you know.

3) Romance: a humorous update for a Wednesday:

Ever since his success with Scarlett O’Hara, Admiral Byrd has been out there claw-waving up a storm. Melanie Hamilton spends just about all her time inside the live rock. Yesterday afternoon is the first time I’ve seen her out of it in weeks. I think she took to hiding out in the rock when Scarlett O’Hara was living in the nursery tank. With Scarlett temporarily gone, Melanie was the total focus for Admiral Byrd. I don’t think she liked that.

Anyway, after giving birth, Scarlett O’Hara has been eating almost non-stop. I think she finally slowed up a bit yesterday, but she’s still pretty ravenous. In fact yesterday, I dropped a shrimp pellet in the tank and Scarlett scrambled up and caught the thing in mid-drop. It never even touched down on the gravel. And she’s pretty good. No fumbling and bobbling the shrimp pellet. She spotted it, she jumped, clutched it to her chest and landed on her feet, eating the pellet before she landed. She could probably earn a spot as an outfielder for the Red Sox.

Unlike Melanie Hamilton, Scarlett hasn’t been too concerned one way or another with Admiral Byrd’s where-abouts. She doesn’t run from him, or toward him. She just eats. Still, I don’t think she’s averse to his presence as she’s spent a fair bit of time in his lair, the fake rock cave, while he walks around waving his claw. I have to wonder if he realizes she’s sitting in his house?

Last night I turned off the tank lights, shut off all the house lights and went upstairs to bed. A little later I had to come downstairs for something and walked by the tank. Even in the dark, I could see Admiral Byrd standing there on his gravel hill, waving his claw. Total darkness, but the crab is still out there trying to get the attention of the ladies of the tank. What dedication.

He is also very funny in his pursuit of Scarlett O’Hara. He climbs to the top of the live rock, to wave his claw of course. Yesterday while claw-waving, he caught sight of Scarlett down on the gravel next to the live rock. He stopped waving, tip-toed to the edge of the rock, peeked over the edge at her to see which way she was going, then, like a teenage boy in love, scrambled down the rock and followed her around all the while waving his claw.

So watch out Scarlett, Admiral Byrd is peeking.

The Post – The Fiddler Babies are Dead, But We’ll Start Over And Prove Horseyhannah Wrong!!

March 10, 2008

The fiddler babies are dead.

I am sad, because I really did like the fiddler babies. I looked around on the web last night for clues to their demise and that’s when I got ticked.

The Discovery Channel’s Animal Planet Online Forum had a discussion of how to raise fiddler crab larvae. “Horseyhannah,” a senior member on the forum basically told a member who asked how to raise fiddler larvae that it’s so hard and requires hundreds of thousands of dollars of equipment to simulate ocean environments, waves, tides, etc. so it’s really not possible. Horseyhannah told the person to just enjoy the adult fiddler crabs and don’t bother to raise the babies. Needless to say, the person asking the question was polite, said thank you, agreed it will probably be hard, but would still like to know horseyhannah’s info source…just in case she decided to raise them anyway. My answer to that person is: GO FOR IT!!!! PROVE HORSEYHANNAH WRONG!!!!!

In fact, I am determined to do just that. In my book, Horseyhannah has thrown down the gauntlet and I am determined to prove her wrong.

I will concede failure on this first attempt. I am sad as I was so looking forward to having some fiddler grandchildren survive. I was frustrated and disappointed because contrary to the advice above, I think it was not only possible, but it was happening. Because I lost them so quickly, that tells me something overwhelming happened in the tank to kill them all off at once.

To review, by Friday afternoon, there were no babies moving around. It was a rapid decline, and up until that point, we still had quite a large number alive. I have to conclude it was a water quality issue and I think the biggest culprit was the live phytoplankton. But to go through this methodically, let me look at several things. If it were salinity, ie they didn’t like the marine environment I don’t think they would have lived that long in it to start with. I suspect the following things were problems:

1) I used gravel and we did lose MANY babies because they burrowed into the gravel crevices and died there.

2) The nitrite levels in the water spiked suddenly and got very toxic. Thoughts on this point:

a) I didn’t get the tank set up early enough to have a mature and well-functioning nitrogen cycle.

b) I either fed them the wrong food, or too much, or both. The wrong food or too much food meant it didn’t get eaten, sat in the tank and rotted. OR it created a huge algae bloom that raised nitrite levels beyond a tolerable level.

c) I didn’t change the water fast enough once I realized the nitrites were a problem, though given the phytoplankton issue, I was probablly fighting a losing battle from the beginning.

d) I no doubt lost babies doing the water changes because my only option was to bail water out of the tank and pour it down the drain

So boys and girls, what have I learned from this first attempt that can be done better next time?

1) I will use calcium sand not gravel. Aside from the fact that the babies won’t get trapped in the substrate material, the calcium sand will provide enough calcium for the babies to stay healthy during many molts.

2) Figure out the right food and amount. The gentleman from Finland whose article I quoted a few days back (he raised the Red Clayed Mangrove crabs) fed his larval crab Artemia…brine shrimp. He had a hatchery right in the tank to have a fresh supply. He also used something called JBL Nobilfluid for when the larvae were too small for the brine shrimp. This product is probably similar to the Small Fry liquid food I was using. It it made by a company in Germany and I’m trying to find out if it is marketed here. It has 50 different vitamins and minerals as well as brine shrimp and is geared for newly hatched aquatic animals too small to tackle live brine shrimp yet.

3) DON’T USE LIVE PHYTOPLANKTON this time. In spite of an almost 50% water change, I could not get the nitrite levels down. In fact, they kept rising. Now I am finding information that phytoplankton excrete nitrites. The better the phytoplankton did, the higher the nitrites. And with each feeding I basically inoculated the tank with more. I created my very own algae bloom which released such high nitrite levels, the babies were doomed.

Frankly, the tank seemed to be doing okay until I started using the phytoplankton. I would feed the liquid Small Fry food and while the tank would be cloudy initially, it cleared quickly, telling me the babies ate the food. At that point, in spite of it being a new tank with an unestablished nitrogen cycle, the nitrite levels stayed pretty low. However, once I started using the phytoplankton, the tank got cloudy quickly, the nitrite levels spiked, the water had a greenish tint, and the larval crabs numbers dropped dramatically. So, NO phytoplankton.

4) For water changes, instead of bailing water out, I will use the water bubbler as my “filter” to keep the babies in the tank, and let gravity siphon water out of the tube. I have the bubbler’s pump set up beneath the tank and have a regulator valve in the line to keep water from back-flowing from the air bubbler, into the pump. If I remove the valve and let the tube sit in a bucket, it will slowly siphon off water through the bubbler. This should let me slowly get water out for changes, without bailing larval crabs out of the tank and sending them down my kitchen drain.

So. I will start over. Admiral Byrd is doing his part, trying to get Scarlett O’Hara to notice him. Scarlett O’Hara has been eating and hanging around Admiral Byrd’s cave den. I figure it’s only a matter of time before Scarlett has eggs again. Therefore, tomorrow, I will take down the nursery tank, clean it out, get some calcium sand, and get that tank up and running again with the live rock in it, and get that nitrogen cycle stable.

We are going to try this again! My husband and I would love some fiddler grandchildren, πŸ™‚ and even he said that we must prove Horseyhannah wrong!!! Stay tuned.

The Post: Fiddler Update – From Periods to Commas

March 4, 2008

Just a brief note today – buried in writing work, bills, and car stuff….reality creeps in. πŸ™‚

The fiddler babies continue to thrive. I notice the numbers are down in the tank, and we also noticed they seem to congregate on the right side of the tank, near to the live rock. They swim in and out of the live rock crevices, and some do wander to the other side of the tank to investigate the water filter which is not running at the moment. They probably figure it’s another cave because any babies over there tend to hover under or behind the non-running water filter. But even as tiny guys, they know to keep to shelter.

My husband diligently checks on them with the flashlight and noted that they are bigger…he commented that since birth they have grown from “periods” to “commas.” It will be interesting to see how many survive. The tank is “ocean” level salinity now at around 1.020. I’ll keep it there until the 17th, which will be two weeks “in the ocean” for the guys. About that point I will start doing water changes and bring the salinity slowly back down to the brackish level I keep the adult tank at: 1.010-1.012.

I am keeping an eye on the nitrite levels in the babies’ tank since it’s up quite a bit. I added Amquel to lower the nitrites but I never really see that happen with that or Prime. I sometimes wonder if the solutions to bring the nitrites down are really “placebos” for the owners of the tanks? In any event, monitoring water quality, especially since I’m putting liquid food into the babies’ tank 3 times a day.

The adult tank has been “business as usual” – Melanie Hamilton spends most of her life hiding inside the live rock, Admiral Byrd is ALWAYS waving his claw these days, and about the only difference is Scarlett O’Hara. She must be recovering from “pregnancy and childbirth” because she has NOT stopped eating. She is shoveling in shrimp pellets and picking algae off everything, with both claws at once. She gives “two-fisted eating” a whole new meaning. It is non-stop, almost “frantic” in its intensity. I guess she is making up for lost time and nutrients. Otherwise, she seems fine.

That’s the goings-on today. Working on the next Under the Pier installment, hopefully to be done for tomorrow. Need to finish some chapter revisions first. Stay tuned.

The Post – Extra!!! We Are Grandparents!!! Scarlett O’Hara Delivers

February 29, 2008

I came out of the gym and my cell phone went off – the vibrating beep to indicate a text message. It apparently came earlier, but given the facility is blocked I only just received it. My husband sent it – a few simple words: We’re grandparents!” I understood immediately – our pregnant fiddler crab, Scarlett O’Hara delivered her thousands of babies.

When I left this morning, she was wandering around, not really interested in eating. Just walking around. Ed noted the same thing before he went upstairs to do some work. When he came down, he said she was just sitting there eating a shrimp pellet … and she was skinny. He did a double-take and noticed the babies were gone from her abdomen, and all these little teeny really teeny black dots, floating around the tank!!!

As soon as I got the text, I raced to PetsMart to pick up the liquid baby fish food called “Small Fry” and raced home. Did you ever notice how many asleep drivers there are on the highway when you’re trying to get home fast?

I quickly got Scarlett out of the nursery tank as my husband reminded me, because at this point, Scarlett’s maternal instincts are probably done. In fact she may view them as floating “cheeseburgers” and start munching. So I moved her back into the main tank. It was like she never left. Not even a second to re-adjust for her. She just walked over to the live rock and started picking off algae and eating. Kind of like “Ahhhh – good to be home.” I don’t think Admiral Byrd has noticed her return yet. Not sure about Melanie Hamilton. She’s been in seclusion since Scarlett O’Hara left the main tank, probably hiding out from Admiral Byrd who has been waving his claw non-stop these days. I expect Melanie may be relieved to have Scarlett back.

Anyway, just had to let you all know she has successfully birthed. I will keep you posted on what happens from here. We’ll see how many, if any, of the babies survive!!! πŸ™‚

The Post – My Husband, Alias Fiddler Crab Midwife

February 28, 2008

Again I will note, it is my husband who thought of something crucial. I’d finally gotten the new tank so the water is clear, the nitrites aren’t too high, Scarlett O’Hara is calm and exploring the tank. I got the main tank’s water changed, so it too is in great shape. Feeling satisfied with the world, I commented that now all we need to do is wait for the birth.

My husband turned and said: “I’ve been meaning to ask you something that bothered me. You have the water filter running in the nursery tank. When the microscopic babies are born, won’t they all get sucked into the filter material?”

“OH MY GOD.” The man is right. We’ll come down some morning and Scarlett will have delivered and there’ll be no babies in the tank – just this primal cry of the thousands emitting from the cloth and charcoal filter material – the crab baby equivalent of “Oh the humanity!!”

I first thought maybe I could just pull out the filter material and just leave the water pump running, but again, my engineer husband said, “Well that will be okay I guess while they’re microscopic. But what happens when they start to grow and get a little bigger? They’ll get sucked through the pump and won’t that grind them all up?”

“OH MY GOD again.” You know, for a person who started this whole thing out with “So, we’ve spent $4 on fiddler crabs and a $100 on support gear,” and laughed at the endeavor, he is the one the babies should thank if they make it because he is the one paying such close attention to their every need. When I hedged about spending yet another $30 on a tank heater, he was like, “But won’t they need heat?”

In any event, I ran to Petsmart to buy a tank bubbler. There’s all kinds – wands, rocks, bars, then there’s pumps – all kinds of those, not to mention you have to buy the right pump to handle the volume of your tank and the right sized wand to stretch across your tank, then there’s the check valve you have to install if the pump is going to be below the aquarium instead of above it – keeps the water from backflowing into the pump in case of power loss….you get the picture. I finally settled on a pump for aquariums up to 20 gallons instead of 10. Wanted something with more power to push air in there. And I selected a wand to extend across the back of the tank to create a curtain of bubbles. I thought that might circulate the oxgen better than a bubble rock. It won’t filter the water, but hopefully the huge live rock and the bacteria I’ve already seeded the tank with from the old filter backing, will be enough to jump-start the nitrogen cycle without the filter running. The bubbler will give them fresh air. So, keep your fingers crossed.

At least Scarlett O’Hara seems to like it. She climbs up on the wand and sits there with bubbles flowing up around her. I hope she thinks it’s “surf” and releases the babies soon. My husband wonders if she is scurrying around the tank so much because it’s getting close and she’s frantically trying to find that right spot to let them go and be carried out “into the open ocean.” Sigh.

Truly, those fiddler babies owe him a lot. He is the true fiddler dad. Admiral Byrd may be oblivious and not care, but my husband surely does. It’s that whole “Caring is Catchy,” thing.

The Post – Nursery Update, Ethics, Parenthood, Friendship, and Just Being a Mere Mortal

February 25, 2008

Just a quick note this morning as I’m on the run. The next installment of my author journey is partially written. Those take me a bit more time. Pondering, reflecting, remembering. Lots to sift through. So those will resume this week.

For now, just to update – Scarlett O’Hara is still alive in the new tank – the “nursery.” Frankly, I was worried. I’d have felt better if I’d set that tank up last week and it had a week to run and settle out. I just hadn’t come to the point of “embracing” trying to raise larval crabs and when I did finally decide this weekend to try, it seemed like birth was imminent. Kind of a go/no-go response needed to be made ASAP.

Last night she just wouldn’t settle down in the new tank. Kept running back and forth, kept trying to climb the sides of the tank. Was there something wrong with the water that was hurting her? All the parameters looked great, in fact the water in the new tank was better than the original – that one’s overdue for a water exchange and the nitrites and nitrates in that tank are rising. So this one is actually healthier. However, certainly there’s other parameters I can’t measure. So my worry was that I’d put her in something I thought was better for her, but maybe I was killing her and couldn’t tell?

I wondered if she was just disoriented and couldn’t find a place to climb out of the water to get air. I noticed air bubbles escaping from her mouth at one point and was afraid she would “drown.” She has this lovely live rock with all kinds of crevices she could hide in, better than her old live rock, AND it’s much bigger so she can climb on top of it, but I thought that maybe in her stress she couldn’t find it. So I scooped extra gravel out of the original tank and put it in the new one and built her two gravel hills so she could walk up the hill and be partly out of water. She found them, but that didn’t seem to be the problem. She just kept running back and forth and climbing the walls.

My husband wondered if she simply couldn’t understand why the sides of this tank were so clean and where was all the microscopic algae she likes to eat? The other tank, though the glass sides look clear, apparently have microscopic algae on them because the crabs are always “picking stuff off” the sides and eating it.

Or maybe she was just so stressed out, she couldn’t relax and would kill herself with exhaustion?

I also noted last night that the formerly clear water in the new tank was now cloudy. I was convinced something awful was taking hold and maybe the live rock had something bad in it. If so, you would expect the nitrites to be rising. I repeated all parameters last night and the water looked good.

So by this point, who is more stressed? Her or me?

My husband said little, just said “It’ll be what it’ll be. You’ve done all you can.” I told him it’s not easy being “God.” He patted my back and said “At least not a God who cares.”

Anyway, I struggled with “should I just bag this whole thing and put her back in the original tank?” I decided not to add any more stress to her by moving her back. One of those – just let it go and see what happens, moments.

This morning the tank looks less cloudy. My husband said he came down and she was sitting quietly in the water, “tending” to her egg mass – ie – giving it pushes and pokes, as if turning them. When I came down, she had found her way to the top of the live rock and was just sitting there on top of her world, soaking up heat from the lights and appearing totally relaxed. (Or is she dead? Should I poke her? πŸ™‚ Just kidding).

All joking aside about my being so worried, I guess I felt guilty. As I said to my husband – Did I put her at risk of dying because I so wanted to try and raise the babies? Did my ego cause harm in this and should I have just left it all alone?

The ethical questions are never clear or easily answered. It’s like being a parent. You try your best, knowing that even when you do, you don’t know if you’ve made the right choices. And in your less than perfect moments, and we all have them, you wonder, will they be okay? Why does God entrust such a big job to mere mortals?

I think Lee Woodruff’s final comments in her book, In An Instant, apply here, at least for being parents, maybe not for being God to fiddler crabs. She worried about how her kids were affected by all the turmoil and intensity when her reporter husband, Bob, was in the hospital with a head injury. She had to be away for long periods to be with him. Things were in an upheaval even though family and friends were looking after things. I so loved her observations, because they are the truth. In thanking her kids she added:

“May you always remember that there are no perfect parents, just mothers and fathers doing the very best they can. And there are no perfect spouses either, just those who love each other enough to stand by “for better or worse.” Don’t be fooled: that kind of endurance is, perhaps, the greatest expression of love.”

I think she could only come to that lesson because of the messiness of life. I think it’s the messy low moments that teach us the most about being human, and about understanding the “human moments” in others. Those times teach us about being compassionate to ourselves and to others, especially when life is at its least pretty. We all want to look like we’ve got it together. Sometimes we do. Sometimes we don’t. Life gets messy. Thomas Moore, a former Catholic monk, in his book, Care of the Soul, I book I read, reread, dog-ear, highlight…in three different colors, quotes something from the Renaissance humanist Erasmus, that applies. Erasmus wrote in his book, The Praise of Folly, that “people are joined in friendship through their foolishness. Community cannot be sustained at too high a level. It thrives in the valleys of the soul rather than in the heights of spirit.”

So, from one very imperfect human, friend, wife, mother, fiddler crab God, go gently into your Monday. It’s really okay, no matter how it goes.

The Post – Is Birth Imminent?

February 24, 2008

I will be returning soon to the evolution of my novel, Under the Pier, but given the goings-on here, I have to take some time to tell of events unfolding in the fiddler crab world.

I decided to see if it is possible to raise at least a few of Scarlett O’Hara’s and Admiral Byrd’s babies, should they survive birth. It’s a long shot, but I want to try. Scarlett looked really pregnant yesterday – that abdomen of hers is large and when she pushes at it, it’s like jelly. I have these observations again from my husband.

It is TRUE LOVE when your husband acts as midwife for your pregnant fiddler crab, keeping close eye on her while I ran out today to get a chunk of live rock for the aquarium. He even called me on my cell phone at the aquarium store to tell me that Scarlett was picking at the larval mass, pulling out a brown thread here and there and planting it in the gravel. He felt birth was getting close and I should hurry home with the live rock. I tell you, is that a friend or not? How many people would call you on your cell phone to let you know your fiddler crab is getting ready to deliver? πŸ™‚

To back up, we went to Petsmart last night and picked up a new 10-gallon aquarium, tank top, light, light bulb, thermometer….. yes, another whole set-up. My husband is laughing but then, he is a geek, just one with different interests, so he respects this endeavor I’m involved in.

In fact, he is working on setting up his own blog that will have all kinds of tweaky things that reflect his interests. When it’s up and running, I’ll be sure to mention it. He finds the most unusual and interesting things out there. To give you a sample of the man, when we are out on a date it is not unusual to walk through the parking lot and have him explain to me the mechanisms for the inner workings of car backup lights and such. I just love it. Going somewhere with him is always interesting and an adventure. Sometime I’ll have to share how he and I hunted down the overgrown boarded up command bunker for a former Nike missile launch site in Newport News VA. πŸ™‚ But a story for another time. Those are the kinds of dates I love. Anyway, I’ll let you know when his geek site is up and running.

To get back to fiddlers, I spent last night setting up the tank. This time I started with distilled water. We have a small water distiller and I proceeded to use up our drinking supply to make up salt water for the “nursery tank.” Mixed up Instant Ocean powder in the distilled water, set up the filter, and within a couple of hours, got the water parameters just about where I wanted them: pH 7.8, alkalinity 180, hardness >300, chlorine, Nitrite, and nitrates all zero. Salinity was about 1.008, a little lower than I wanted because I want this tank’s water to be an almost exact match for the main tank.

This morning I used some marine buffer to bump the pH up to 8.0 and alkalinity closer to 300. Added a bit more Instant Ocean to get the salinity up to 1.010. I seeded the new filter with a strip of “very well colonized” filter material from the old tank to jump start the nitrogen cycle, and brought home from Fish Pros the MOST amazing chunk of live rock – ALREADY had all kinds of marine invertebrates and microscopic algae on it because it had been in another tank that had just been dis-assembled. So, the live rock is well underway growing organisms and probably has another dose of nitrogen-fixing bacteria ready to go.

I debated about what to do with Scarlett O’Hara, leave her in the old tank and struggle with where to release her babies or put her in the new tank with plenty of room for all. Finally decided to take a chance and I’ve moved her into the new tank. She seems to be doing okay in spite of being rattled by being moved. I’m hoping it didn’t disturb her too much. It always shakes them up a bit to move them around. I have done my best to make her a good nursery and here she is free from Admiral Byrd’s claw-waving. I even took the heater from the old tank and gave it to her in the new one. I ordered a new heater for the main tank which should be here Wed. But I figured Melanie Hamilton and Admiral Byrd will be fine for a couple days with the tank lights to keep them warm. I figured “momma” needed it more.

By the way, the tank heater I use is a small one geared for 3 gal aquariums. It’s pre-set and can be mounted sideways with suction cups, and there’s no risk if it touches the gravel. It’s a Marineland Shatterproof Heater (10 watts) part number VTMD10 and found it online at That Pet Place.Β  Since my tanks are only a third full of water (to allow space for the crabs to get out in air), regular heaters won’t work. Not enough water for them to be fully submerged. And regular heaters are generally large and have to be vertical.Β  This guy is short and can be sideways. Keeps the tank in the range of about 78-80 degrees F. So for what it’s worth.

So…the nursery is up and running. So very much hoping that 1) Scarlett will do okay in the new tank; I would feel terrible if she doesn’t make it because of the move 2) the babies do okay.

Then all we have to worry about is how to sell off many many many many many grandchildren? πŸ™‚ I’ll keep you posted.

The Post – How Long Do Fiddler Crabs Stay Pregnant?

February 23, 2008

I spotted this question on a Google search and decided to follow up on it. It has been the question in our house – Scarlett O’Hara seems to get bigger every day with the larval crabs she’s carrying. How long will she carry them? What will she do with them? I’ve learned that female fiddler crabs usually like to hang on to the babies until the right set of tides and conditions so that their babies will be carried out to the open ocean. Apparently they do this because the larval crabs stand a better chance of finding food, and of not becoming someone else’s food, out in the open ocean. That gives them the best chances for reaching adulthood.

The question in our minds here is: we have no outgoing ocean tides in the “aquarium estuary” so when will she release them?

We’ve noticed she keeps hanging out on top of the water filter. In fact yesterday she was deep down INSIDE the water filter. She’s also been ripping the filter backing apart and eating whatever she’s pulling off the fibers. Since fiddler crabs like to eat a lot of microscopic algae, I assume that’s what she’s found. I keep wondering though, is she going to release her babies in the “currents of the water filter?” If so, I wonder how she will decide which currents are “outgoing tide” to that imaginary open ocean we don’t have. πŸ™‚

Anyway, two good articles I came across in my search:

1) When ‘in a pinch’ won’t do: Ultra-picky female fiddler crab cited in UCSD (Univ of California at San Diego) study.

Apparently the female California fiddler crabs are VERY picky about their mates and have REALLY high standards for what kind of “house” the male is offering them. On average the female passes up 23 offers before finally selecting a male. In one case a female passed up 106 offers before choosing her mate. Now…I don’t know who to be more impressed with – the female fiddler crab who passed on 106 males before choosing one? Or the human researcher who followed this female fiddler crab around and kept track of how many males she turned down before choosing? In any event, an interesting article on the life cycle habits of the California fiddler crab.

2) The SC and C FAQ Database: it has a large number of questions and answers about crabs, shrimp, and crayfish. Question # 16 is about 3 pregnant female fiddler crabs and how long their gestation period lasts. Apparently in an aquarium, the female will release the eggs in about a week. We shall see. …Also it has information on what to feed the newly released babies, which might actually let them survive in an aquarium and grow to adults. Hmmmm 100,000 grandchildren. Needless to say my husband is thrilled with the news we might actually be able to help the babies survive in a tank! πŸ™‚ Now all I need to do is find micro-plankton, like Infusoria, to feed to them…..
