He (the owner) had it marked at $100 as an emporer angel. I should have done more research, but I asked the owner if he was certain it was an emporer and that I thought emporers had a complete circle pattern. The owner told me that the circles develop in the later stages of change as a juvenile. I asked the owner if he had a book on marine fish so we could be sure, and the pic in the book showed the juvi emporer w/ full circles. There wasn't a pic of a Koran in his book and he swore up and down it was in fact an emporer. I bought the fish for $90, brought it home started acclimation and did some research. After I got your response and did more research I took the fish back to the LFS 25 minutes away. The owner was mad and honestly I didn't think he was gonna refund my money. I told him I was certain that the fish was a Koran and he laughed and said "certain huh". He himmed and hawed and finally threw my check back at me. I won't buy anything else from him again because of this. I have a 240 gallon reef tank that is full of coral, I don't even want to know how much money he is losing over this. I told him I just want to be sure that I'm not getting an "adult ugly coral eating monster". I'll take my chances with an emporer as they are stunning as adults. My tank is 5 years mature and has plenty of live sponge and algae for a large angel to thrive. I'm ordering one tonight from swf.com
