Hello just curious i just finished the qt moved all my fish to my dt 80g and the hippo tang which is the size of a quarter maybe abit bigger keeps chasing my clowns and sort of lunging him at them swimming under them is this aggression? Do they pick on other fish with their spines or by actually biting them cause there is no biting at all just him swimming at the other fish underneath them. The hippo and clowns are about the same size.
