I have 2 male cresteds in a 20 gallon vertically oriented tank that is divided down the middle to keep them seperated. But lately they have been going inbetween a crack to go on the same side together. I always thought males would fight but they seem to always be next each other and prefer it that way. I can secure the structure better that divides them so it doesnt happen but im wondering if it even matters. They haven't faught yet and its definately easier to deal with if the tank wasnt divided to begin with. Do you think its possible to keep them together?
