Saw a couple at the LFS, asked the guy how big they got and he said 8" and that they would do great in my 58 gal reef tank, that they're mainly algae eaters and very peaceful, leave coral alone. Anybody here have anything to add to this? Dispute about this? Beautiful fish, I'm looking at them seriously, knowing well that it will use a lot of my bioload. I really would like one large fish and possibly two or three little fish. I'm putting together as we speak a 20 gal sump for this tank. I love the look of the tangs, but I'm wary of stifling one. If I could find a smaller one... or a tang-like fish (which is why I really dig these rabbitfish)...
