Am I looking up the wrong fish? When I search yellow tail tang it comes up with purple tang and It says minimum tank size 125.
ctenochaetus flavicauda = white tail tang
You're on the edge basically of minimum tank size. Some would say you can, some would say you can't. Up to you.
I'm not going to do a yellow tang. I was looking for some bigger fish that I could have though that are reef safe. I suppose I could post the list that I have so far. I do like the look of the white tail tang.
