Naso Lopeza tang. Will grow to 20 inches. I almost bought one the other day for my 90 gallon because he was so interactive and was interested in looking at me in the fish store....great personality, but do your reasearch next time before buying. He will need about a 180 gallon tank when he grows up! You can always give him back to the fish store when he gets too big, but, if you are like me, I find it difficult to do because I become attached to my fish after a while.
