the Oceans fish, that's the exact fish I was thinking of. Beautiful fish but it needs something big to swim in.
Call me the tang police, but IMO Zebramosa sp. are much better suited to aquarium life
The problem with the hobby, and to the fault of LFS when you see Naso's and unicorns tangs and so forth they are fairly small specimens that do not really give you an idea of what they are going to grow up to be.
In the end this is just my opinion, everyone can stock their tanks however they see fit, I just know that unless I had a HUGE tank I would not even consider one.
