I don't think they will eat their young but you never know i have been raising shellies for some time now but my main occupants in a 55gal is Neolamp Multifasciatus and Neolamp Brevis..
I just setup a new shellie tank tonight with the Neolamp Ocellatus in a current 20gal high that i had been holding some fry in, here are a few photos of my newly obtained Ocellatus from earlier today..
I have 6 total but they are still tiny so i couldn't tell you what sex they are..
