Any tips on fish aggression? We have an Achilles tang who has been totally fine with everyone in the tank. We just added our copperband tonight, lights out, and as soon as he noticed my copperband he attacked and wouldn’t leave him alone. We got the Achilles and put him in an acclimation box but I’m at a loss on what to do. I can’t really rearrange the aquascape as we have a bunch of corals. Other fish are fine with copperband
