imo redtails, bluethroats and pinktails are great reef dwellers. They are also the most economical and easiest to get at 2-3" in size. I dunno how large they can get when grown in an aquarium enviroment tho. A 120 could prove to be too small down the road.
When the clown tang and trigger grow it's gonna be interesting.
