I have this PB in my qt tank right now and I added a sailfin tang and he started attacking it which was a given so I separated them. I'm just worried about aggression toward my fish in my main tank like my copperband so I'm wondering if I can solve the aggression or should I just trade him in for a bristle tooth tang which will proubably end up being much nicer. He's a fat healthy monster rn so I'm afraid of the damage he'll cause.
