Clown Trigger

 One of the most popular of all aquarium fish! The clown trigger is black with large white spots on the lower half of the body, a yellow saddle around the dorsal fin, yellow rimmed mouth, and a white line horizontally across the face. The fish can reach up to about 50 cm (20 in) in length. It has strong jaws which can be used to crush and eat sea urchins, crustaceans and hard-shelled mollusks. Like many other triggerfish, it can require a large aquarium and be aggressive towards other fish. It should not be kept with small fishes. It will also prey on invertebrates in the aquarium. This fish can become tame enough to be hand-fed, however one should beware of the fish's sharp teeth.
