I've had one for almost a year. It's a very fast grower and very friendly to everyone in my tank. He's with a blue hippo tang, purple tang, powder blue tang, 2 yellow tangs, Atlantic blue tang, convict tang, flame angel, Xmas wrasse, yellow coris wrasse, orange back fairy wrasse, and a few other fish. He doesn't bother anyone not ever new comers. He eats like crazy anything I put in. It's been in a 150 for almost 11 months and is pretty much starting to out grow it. It will b moving to a 220 soon. Got it last November at about 2" and is now easily over 6".
