Comet

This rather solitary fish lives hidden most of the time in coral reefs where it feeds on small planktonic crustaceans and young fish. When it is frightened, it darts into a crevice head first, leaving just the tail end of its body exposed. Its back has a black mark on it, which fools the predator into thinking that it is the head of a pearly moray eel! These fish are bred in the aquarium.
