Well a few hatched last night and I expected to find a million this morning but no such luck. The female still has her eggs so hopefully tonight or tomorrow. I have a kreisel ready to go and I'm grabbing some rotifers tomorrow.

Just hatched between 11:30pm and 1:00am. They are in a kreisel right now with rotifers although due to their size, if they don't take the rotifers I'm going to try bbs. Pics coming tomorrow including microscope pics!

They're eating bbs! Pics to come with full bellies and/or larvae holding bbs while they eat them.

Found ~20 dead today presumably because they did not start eating soon enough but could also be other causes. Pics:

Not really sure of the reason but most of the larvae have died off. I have a feeling it might have been a food issue although I know they were eating. I'll try again with the next round.

Lost the female today. No idea why since all parameters are fine and she has been eating like a pig. :/

Oh no! Did you find her body, or is she just missing? Were you able to sex them through physical characteristics other than carrying eggs so you can look for another female?

Yeah I found her upside-down. The female has a significantly larger and more rounded abdomen for holding eggs so I think I might be able to sex one.
