However, the tang is harassing the new butterfly.
I do hope you know that the yellow tang and butterfly are going to outgrow your tank eventually. Butterfly aren't as hardy and they NEED excellant water condition!!!! I hope your not having a reef tank, cause most of them are not reef safe. By rearranging rock works will establish a new territory and by removing the tang and reintroduce with the new fish at sametime will establish a new territory also. Leave the lights off during this process and turn the lights on an hour later. Hope this work! :happyfish
