I know what you mean.. Tigers fighting/establishing rank, can go on for ages. especially if you only have 2. As soon as the dominant one declares himself No.1, he will still bully the other one continuaously if there are no others to spread aggression. So best to have 5 or moreFractal;3960131; said:Yeah I did quite a bit of reading, but having kept more aggressive fish than datnoids before I wasn't totally ready for this type of aggression. With my old Jack Dempseys they'd beat the hell out of each other and then it's over after one cowers in the corner. Frankly I've had piranha's that were more friendly than this Datnoid lol.
I have an acrylic cube thing that I've already drilled holes in and plan to keep the little bastard in there.
good luck, keep us updated.
