Description
A group of smaller surgeonfish known for their fine, brush-like teeth used to graze detritus and microalgae from rocks and sand. They have a more subdued but attractive appearance, often with speckled or striped patterns. Common species include the Kole Tang (Ctenochaetus strigosus) and Tomini Tang (Ctenochaetus tominiensis). Excellent “clean-up” grazers in reef aquariums.
