The Post – New Fiddler Babies

I was amazed to see babies born before Monday. Monday was 2 weeks to the best of my knowledge. So she delivered a couple of days earlier than I expected.

Anyway, yesterday started with me doing a 30% water change as nitrite levels in the tank since Scarlett has been in there, have been hovering between 0.5 – 1.0 ppm. I kept the water filter running to give the water the best chance of staying nitrite free and letting the nitrogen cycle mature.

This evening though, I noticed that Scarlett was very agitated. She kept running back and forth in the tank, climbing up onto the air bubbler and waving her claws in front of her as if trying to spread something in the water. There did not appear to be anything in front of her though. I noticed that the center of the egg mass seemed to be swelling. Given that, I went ahead and shut off the water filter.

For the next hour or two, Scarlett O’Hara kept moving around, seeming very uncomfortable. Around 8:30 p.m. I looked over at the tank and noticed she was sitting quietly in the front of the tank eating. She seemed “slimmer.” Looking closer, I realized, she no longer had the egg mass. So I missed the delivery again. However, a quick look around the tank and I could seen thousands of tiny little dots swimming around.

I fed them a small amount of Small Fry and ZooPlex. I wondered if this will go okay since I couldn’t get the nitrites to zero before they were born.

This morning I got up and looked at the tank. It was a white cloud. I thought, “Oh God, the water quality got worse with all the babies in there and the nitrites are probably through the roof.” I looked at the ammonia monitor and it is in the safe zone. I shined a light into the white murk and could see thousands of babies swimming around. So they’re still alive and ?healthy.

Wondering why the tank is so cloudy, I decided to recheck water parameters:

pH 8.0 – good; alkalinity 300, hardness >300, chlorine 0 – all great results, AND the REAL KICKER OF ALL: NITRITES AND NITRATES ZERO!!!! Puzzled, I repeated the nitrites test using a tube test instead of the dipstick. Again – nitrites are ZERO!!

So water quality is actually BETTER??? I looked in the tank and saw all the babies flitting around and MANY on the calcium sand at the bottom. That’s when the light bulb went off in my head. The water cloudiness is “white” like the bottom sand….could it be cloudy because thousands of little tiny guys are bouncing around against the sand at the bottom, eating whatever’s in it (since it’s ground up from live coral…possibly some microscopic food bits there?), and eating it for calcium for their molting?

If they were out in the ocean they’d have “bottom stuff” to dig around in so maybe this is a good thing? Though it certainly makes it harder to see them. For whatever reason, baby fiddlers seem to like to “head for the bottom” – at least some of them. That happened last time with many burrowing into the gravel and dying. So I will see how this calcium sand thing goes. I am PLEASED though that the water quality is so good.

For today – I need to go feed them again and I will need to start raising the salinity to ocean level. If that IS what should happen, they should survive. If not, well, we’ll find out. One step at a time.
