8 or 9 inches, he had a 2 other tank mates but I didn't get their pictures (too fast).
One looked like the body shape of a "tang" (like dory off of finding nemo :rolleyes but wasn't any kind of tang I have been able to find a picture of so far. It was tanish-yellow-white with black stripes and its dorsal fin could be "raise" to make itself look bigger (kind of like an anole lizard's throat)
The other was a kind of parrot fish i THINK? It kept picking up sand and spitting it at the "tang" type fish. lol!
I found the name of the place so I guess if you REALLY wanna know you could call?
-It was over a month ago that I was there... *scratches head*
The "tang" one looked a lot like this one but not as big of a fin on top even when it opened. Most the time while swimming the fin was flat against its body, it only open it as a threat display (i think) to the other fish.:
