I’m thinking of ordering a 4-5” sailfin tang and a 4-5” copper band. From live aquaria. But I’m afraid my 4” purple tang will be a jerk to them. Will adding them at the same time help with aggression? Can I quarantine them in the same 10 gallon tank? Should I wait till I can find them pre quarantined and i am set up to temporarily trap the purple tang?
