Not crazy about mine. Maybe it's 'cause my yellow tang, being the boss makes him a whimp at times. And when he gets wimpy, that beautiful yellow color turns brown in splotches. He can get real ugly at times, yet so beautiful when content, which is the majority of the time. He's going back to the LFS
soon though. He's very healthy though and for the most part, gets along fine with the yellow tang. I shouldn't have got him in the first place, being yellow and somewhat disc shaped. An LFS
talked me into adding him when I thought a vevlet outbreak had passed. I misunderstood him and thought I could return him after a few weeks. He's going back to another LFS
2 might be much for your 90 gallon if you want to add any other substabtial sized fish later. But they are hardy and nice looking.
