Two month ago I added a new clown to my 32 g system (the white one). For the first two days they fought (as expected from clowns) and stopped for about a week. But for the last three weeks they have been doing this routine everyday almost all the time. It always starts with the black one looking around the tank for the white one, then charging it and chasing it around the tank. Now and then the white one will stop and twitch at the black one as the black one headbutts it. When I separate them by putting the black one into a see though breeding cage, the white one will not leave the outside wall of the cage and will twitch at the black on. Neither clown have any visible damage but the white one is looking a little thin and was swimming kinda vertical for the last 30 min (it has recently stopped) so I reisolated the black one. I have tried everything from changing my scape to isolation for multiple weeks. Is this just normal breeding behavior or is this something that will make me need to rehome one of them? Any advice would be greatly appreciated
