Copperband butterfly fish

[JaiWiz]

Okay so today i acclimated a new copperband butterfly fish to my tank to tackle the aipetasia problem i acclimated him for 2 n a half hours and put him in with the lights off. i turned on the lights about a hour n a half later to see how they were mingling and i"ll be damned all my other fish were taking some pretty aggressive runs at the CBB i'm concerned because these fish are already a delicate fish never mind having 5 other fish trying to kick your ass. what can i do all the fish did this to my yellow tang when i first put her in maybe its just a initation kinda thing
