Blue Hippo Tang - are they all mean?

[Coralgurl]

She only nips at the trigger's fins, but they are always doing a bit of a twirly dance. The trigger won't move to the other side of the tank, they all seem to hang out in the same spot, right front.

Ugh, I yell at her to stop but she pays no attention to me. Dam fish.

Would moving her to my smaller tank for a couple of weeks and then reintroducing her make any difference? She's about 3 1/2 - 4" big right now, this is of course assuming I can catch her.
