I would not reccommend one for a reef tank. It has come to my experiences that Lemons, Flames, Coral Beauts are all in the same category. It simply all depends on the one you get. (Whether they were net, hand or cyanide caught) I have had people and books explain Flames to be great beginner fish, real hardy, and hard as nails only to purchase one with vibrant color that ate (After 9 years experience then) die after 3 days and many many laps in a very tight circle with eyes wobbling in their sockets (Quite horrifying for any keeper). The postmortem revealed cyanide from a sample taken behind the gills, little to say this store lost my business. Any time you go to purchase a prized piece (Any fish) whether it be 5.00 or 500.00 put a down payment on it so you can watch it for a week. If your dealer is reputable, he will gladly oblige. It could be that one impulse that either wipes out your tank or discourages you from the hobby...
