The Surgeonfish family consists of fish which are colorful, thin-bodied, and usually have an oval shape. These fish have long continuous dorsal and anal fins and crescent tail fins. The scalpel at the base of their tailfin is very sharp and is used by the fish for protection from predators as well as a way of establishing itself with other fish. These fish are usually seen at reefs eating algae all day long.
I ordered one of these specimens several months back, and I have to say I am very impressed with what I received. The fish arrived healthy and a little larger than advertised. The color was the deep adult color I was looking for, and this guy has been my favorite in my tang tank ever since. My mimic (or chocolate) tang has been a model citizen.
