I have a 20g with a talbot damsel who I think is maturing and turning out to be an butt (yes I know who woulda thunk). It’s starting to kind of target my bar goby when it’s swimming near his rocks. I was wondering if there’s a fish I could add to disperse the aggression perhaps like a royal gramma, 6 line, clown, etc. Tank inhabitants are the talbot, a neon goby, bar goby, two hermits, nass, turbo, trochus. Has plenty of pods if a wrasse is ok.
