Genus

Common name: Triggerfish

Scientific name: Xanthichthys

Xanthichthys, commonly known as triggerfish, is a genus of marine fish known for their unique rhomboid shape and ability to lock their dorsal spine as a defense mechanism. Members of this genus are popular in the aquarium trade for their vivid colors and personality. They are generally hardy but can be aggressive, so they should be housed with caution in a community tank. Triggerfish require ample swimming space and a varied diet, including meaty foods and, for some species, algae.
