Triggerfish are fascinating to watch swim with their fin on the top and bottom of their body. They do very well in aquariums that offer them enough space and hiding places. They can be aggressive when more than one of the same species are in the same aquarium. They will eat corals and shrimps so should only be kept in fish only tanks or do well in predatory aquariums. Triggerfish love meaty foods and live foods and grow very quickly.
