yellow tang compatible?

[tran901]

i have a 125 reef tank with a 5" regal and 4" desjardini sailfin. my girlfriend wants a yellow tang in there too. is that possible to have one? or will it get picked on?

Well, the tangs you have already are a lil big for that size tank, especially that desi, which is going to get huge, and outgrow your tank pretty fast.
I bet it's not going to like sharing swim space w/ a new tang either.
I would begin looking at rehoming the desi for sure, maybe swap that for a small yellow.
