I have a number of mysid shrimp in with them that I have put in there with them and its roughly dark in the tank (night time for me).
I do notice that of the 4 I have left- 2 look more normal in activity and seem to show more color while the other two look almost preemie-like. They are super small and almost all white.
They did not hatch in my tank but during transport. Is there any record or possibility that they could have hatched too early? I know the ones that I started with on my own were in their eggs for awhile before they hatched in my tank.
