Clown triggerfish is a species of triggerfish, it is carnivore and mainly eats benthic organisms like molluscs, echinoderms, and crustaceans. They can be found in the Indian Ocean, the western Pacific, and the Caribbean Sea. As a protection against predators, triggerfish can erect two dorsal spines: The first (anterior) spine is locked in place by erection of the short second spine, and can be unlocked only by depressing the second, “trigger” spine, hence the family name “triggerfish”. Triggerfish are very popular in marine aquarium trade, due its exotic colors and passive nature, just requiring a large aquarium. Sometimes, though, they can be aggressive towards other fish, and even the owner, they will also eat small fish and invertebrates. Triggerfish, specially titan triggerfish, can be very aggressive when defending their eggs and aren't afraid to do so with their sharp teeth. The males are territorial and make hollow nests.
