Kleini Butterfly w/ Yellow Tang

[DidYouSayReefer]

I purchased a Kleini in hopes to clear some Xenia from my 110. My yellow tang imediatly went after him. From past experience, an angel that he killed, I knew it might be a problem. The tang is now living in my sump. Are there any chances I can add him back to the DT without aggression? If so, what is a good waiting period. I really don't want to add him back and tear the tank apart again trying to catch him.

Anyone have a similar experience?

i've had problems like this in the past. sometimes it will play out eventually and sometimes it doesn't.

i find introducing it a couple days or a week later in the darkness of the night helps alot. or at least till your klein's butterfly is stable and more confident in the tank.
