I agree with Ahud but at the same time I dont think the space is always the reason. My Male bred once before and it was in a 30 gallon and he was by far the biggest and baddest fish in the tank. The Female would nudge him and let him know its time to get back to Patrol but at the same time he was still the most protective of the fry. She started to eat some of them and I figured she was just doing the mouth washing thing and then the next day she ended up with missing fins. So i removed her and then reintroduced her and he killed her once she was reintroduced he looked at her like an intruder and not his mate. The bond was broken so the Male kept protecting the fry but he definitely killed the Female because she was endangering the Fry.
