looks like mysis shrimp. I have a bunch in my tank they just came with the rock and populated. Much more active and out then pods.
Did you buy one or DIY?
I'm anxious to see how well it works. I have been staying up on hatch night with a light and a bowl to skim the little suckers out. Agonizingly painstaking work when you are talking hundreds of larvae. Lost my first two attempts but currenty have about 100 still alive and starting meta.
It could have been anything, but my best guess is that the larvae were weak due to poor broodstock nutrition. Once I made an effort to really stuff the parents with NLS Thera A pellets and a DIY seafood mix the larvae in each subsequent batch were stronger. Initially most died on the first day or two with 15-30 left that died during meta. The latest attempt has been much better. Larvae were much stronger swimmers from the outset. Some of them were showing a faint headstripe this morning. Now I just have to figure out what to do with 100+ Spotcinctus!
