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!!! 🙂

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? 🙂

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. 🙂 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.  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.  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? 🙂 I’ll keep you posted.

The Post – Extra! News on Preparing the Fiddler Crab Nursery

February 23, 2008

So you’re like me and you’ve got a pregnant female fiddler crab. Now what?

Well, we just came home from Petsmart with a second 10-gallon tank, lid, light, and pump/filter assembly so I can set up a saltwater aquarium in which to put the babies. Maybe I’m crazy for trying to see if I can raise them …?then sell them? but the challenge of motherhood calls. My husband, a geek of a different nature, respects this need in me to see if I can do this. He quietly acknowledged that he would “understand and be willing to fund” a second tank for the “kids.”

The dilemma now is did I wait too long to get it set up and get the “nitrogen cycle” started before she releases the babies? I can take a patch of the filter gauze from my current tank, which is loaded with nitrogen-fixing bacteria, and put it in the new filter to “seed it” with bacteria.

Tomorrow I’m going to Fish Pros in Raleigh NC to get another good-sized chunk of live rock. Between the filter seeding and the live rock, that should get the water parameters in the safe zone and the bacteria up and running quickly. Also the live rock will provide calcium for the many molts the little ones will need to go through.

What I was not sure though was how I would be able to “catch” the babies since I won’t know when she releases them and I won’t know if they’ll be too small to see once she does. Also, should I make the second tank a regular “salt-water” tank to represent the “open ocean” like most fiddler babies go to, or make it brackish like what they’ll end up in? This last question got further complicated by the information I found on the blog below that indicates I should isolate mom before she releases the young. So I have much to ponder tonight while I get this up and running.

I did a search for info on pregnant fiddler crabs and come up with The “Dear Blue Lobster” blog entry” from July 25, 2007. The Dear Blue Lobster site claims to have been answering “your crustacean questions since 2002.” This entry is from someone who is concerned that her fiddlers make have “hooked up” and now what should she do? She is freaking out at the prospect of a 100,000 babies in her tank.

The gentleman who runs the blog gave good technical advice on taking care of the pregnant mom, saving the larval babies, raising them, and even indicated how much/lb. you can sell fiddler crabs for over the internet. The crustacean guru also gave the following emotional advice:

“So what do you do if your female is indeed pregnant? Comfort her. Her man has kicked her out and will no offer care for her children — in fact, he may try to eat them! ….Good luck to you and your Fiddlers. Motherhood is a special blessing indeed.”

Since it is well past July 2007….I wonder how the mom (human) and the mom (fiddler crab) made out with their situation? For myself, we shall see. I am off to set up the tank. I guess I’ll set it up brackish and isolate mom before she “delivers.” I have also emailed Dear Blue Lobster for help on what I should do. I’ll keep you posted on his reply.

I recommend the blog. The crustacean guru is Christopher Chimwish. His site description is as follows:

Christopher Chimwich received his MMN in 2000, specializing in decapod behavior. He is currently surveying benthic decapod populations in the Indian Ocean for his doctoral thesis. Chris answers questions about crustaceans, covering everything from DNA mutation in African crayfish to Fiddler crab sign language.

By the way, if you want to be a real geek, apparently the term for my fiddler crab when they have the brownish eggs attached to their abdomen is being “in berry.” So.

The Post – Pregnant Scarlett O’Hara and the Proud Father

February 21, 2008

I am going to be out of the office today, so a brief, fun posting with pictures of pregnant Scarlett O’Hara carrying her larval fiddler crab babies. Also a shot or two of the proud father, Admiral Byrd, who is STILL waving his claw. I am determined to get a really good shot of him doing that claw wave, but these aren’t too bad.

Here are some shots of “the babies.” They are the brown mass of egg-looking things tucked in that shelf on her abdomen. They’re not the sharpest shots, but then, Scarlett O’Hara is not the most cooperative super-model. She won’t stand still. Also, it’s hard to get a shot where she’s not moving her claws. She is CONSTANTLY shoving food in her mouth – she is a two-fisted, non-stop eater. I guess though, she is eating for a few thousand? 🙂

Admiral Byrd spots me and tries to hide in the corner of the tank against the live rock. The grayish streak is the silicone sealant in corner of the tank. I think he likes to hide behind that strip and also the thermometer strip (not seen) because it blocks his vision of me – that whole “if he can’t see me, then I don’t exist and he’s safe,” mentality? What do you want from a creature with a brain the size of a pinpoint?

The other two pictures are classic Admiral Byrd poses. He sometimes spends all day with his large claw in the air, sometime both claws in the air. While I know he’s either trying to scare me off or encourage the ladies, sometimes when he has both claws up, he looks like he’s paying homage to the god of the tank, the aquarium light above. He is also very pragmatic when trying to show off for the ladies. He’ll have his large claw up to get their attention, while using his smaller claw to shove food in his mouth. A guy has to eat, right?

See you tomorrow!
