Clown trigger fish are brightly coloured fish of the family of Balistidae. They lay their eggs in a small hole, dug in the ground. All trigger fish have an unusual dorsal fin arrangement and are characterised as such. Because of its attractive coloration, the clown fish is one of the most popular aquarium fish. Like many other triggerfish, it can require a large aquarium and be aggressive towards other fish. It should not be kept with small fish that you want to keep. It will prey on invertebrates in the aquarium. This fish can become tame enough to be hand-fed, but you should be aware of the fish's sharp teeth. Triggerfish have flat looking body with an anterior dorsal fin. They can erect two dorsal spines, the first one locks and the second one unlocks. This prevents predators from swallowing them or pulling them out of their holes. When depressing it's second spine it releases the first spine this trigger action is why they are named triggerfish.
