How big?
 

Just wondering how big of a tank would you need to have in order to keep more than one type of salfin tang together? I just found out that my 120g isn't big enough for a yellow tang and scopas tang to co-exist peacefully :sad:

Sounds like a good enough excuse to me to get a bigger tank:lol: Is any tank really ever big enough?

did you try em out together? i've got a yellow, sailfin, purple and regal in my 120

The yellow tang has been in the 120g for about a month or more now and I tried to add the scopas tang 2 days ago and the yellow tang keept attacking the scopas tang so after 1/2 hour of the attacks not letting up we removed the scopas tang and added him to our smaller tank. Not sure were to go from here, I know our 30g is too small for a scopas tang however he seems ok in there for now until we can figure something else out.:eek:
