Genus
Common name: Blue Tang
Scientific name: Hepatus
Hepatus is a genus of surgeonfishes known for their striking blue coloration and bold black markings. The most famous member of this genus is the Blue Tang, Hepatus coeruleus, often recognized from its depiction in popular culture. These fish are active swimmers and require ample space to thrive. They are herbivores, grazing on algae, and can help control algae growth in a reef tank. However, they can grow quite large and are best suited for larger aquariums. They are also known for their sharp 'scalpel' located near the tail, which is used for defense.
