The tank is just filled with live rock and frags of corals from my other tank. Also will serve as a second place to raise the shrimp once they grow.
If they do grow successfully I will buy a 20 gallon tank to raise them till they are larger.
The setup is temporary, just trying to test out the concept.

A couple of days before the birth we always saw what looked like a big thing of fish poop (getting technical here) floating in the aquarium. It was pretty consistent just before the spawns so we're pretty sure that was the egg sack being released to aerate. We didn't always see it mind you, but more often that not. Once hatched you can see the babies pretty clearly, they'd sit in the top 6" or so of water so you can scoop them up. Because of this you really need a typical hob filter so that they don't get sucked into anything that'll kill them. A tank with and overflow doesn't work well. They always hatched at night so just check things in the morning.
As for raising, we used baby brine. Aeration obviously and it needs to be in a tank without any filters/overflows etc. They'll get sucked in. We just used a little 1/2 gallon bowl. The key is to get as many live brine in there as possible and change the water often. These guys don't go far for their food and you'll have a lot of die off at each stage. We got them to the point of having little legs and looking clearly like baby sexies (when they're born they almost look like adult brine).
I'll be watching this closely. The only issue I could see is that with the height of the pico it may get hard to catch the babies and your hob filter might suck them up. I'm kinda curious if that'll happen or not. For my new one I'm leaning towards a 10" tall pico to avoid the issue. Looking forward to seeing how it works.

faerl, thanks for the great info, this is going to really help. I've been looking all around for info but have found very little. One question, how long did it take for the sexy to spawn after you noticed she was carrying eggs? Mine has been carrying them about 2 weeks and a half and she is starting to look ridiculously large compared to the male. Thanks again for the info.
Honestly, I'm not sure. At the time I had about 10 sexies in a 10 gallon tall tank. There was almost always at least one pregnant and I wasn't tracking them like I should of been. I'd guess a few weeks. The sign I always used was the release of the eggs. I couldn't figure out what they were floating in the tank until after a few breeding cycles I noticed that every time I saw them they'd pop out another set of babies 2-3 later.

Where did you buy your satellite fixture?
peytonk, I bought it from a forum member, they show up once in a while the 12" ones.
The sexy is just ridiculously fat, It's been about 3.5 weeks since she has been carrying them. I wonder how much longer it will take before she spawns. I can see the eggs and they are clearer and have some red streaks and 2 black dots in them. Her abdomen is so large that the eggs are now clearly visible all the time because they don't all fit in her abdomen.

thats a high number already, i think leaving the AC on is important, though if you want to use an airstone, that will work too. i bet you'd still see some larva even if you left the AC on.

So here are some photos,
head count ~30,
active larvae ~20-25,
feeding is going to start very soon with bbs, at the moment only rotifers and phyto is available

Got that way by:
Problem algae growth has nothing to do with excess of anything in many natural settings and in most reef tanks its not a nutrient issue, its due to purposely letting it take over. algae is present on zero po4 natural reefs simply where grazers haven't grazed, so how is po4 the root of all invasions?
Quit chasing phosphate. Last decade was nitrate, neither are the key to preventing tank invasions. become your own grazer

What, am I a Postmaster Psychic now??

Now where's my CAO?
Posted 26 January 2011 - 09:04 PM
So I started feeding baby brine shrimp and they immediately began holding and what appears to be eating the bbs. I did a head count and noticed that I had more shrimps than I originally counted. Right now there is about 34 shrimp that are alive. Only 3 so far have perished. The mother seems to be holding several hundred more, I wonder when she will decide to release them.

Now i need to master hatching BBS fast as training for my future breeding endeavors.
