Yep, mine is becoming a bit dominant. He hasn't really roughed anyone up just yet but he's is beginning to really chase everyone. His tank mates are much smaller than he is especially regarding length.
My brother just put up a 90 gallon with plenty of open water and I'm taking the fish to him, probably this weekend.
He seems to be growing quicker than the other fish.
great fish though and if I had a 90 or 120 I would definately consider keeping 3 or 4 of these guys and maybe even breeding them.
Thanks,
