The Gold Ring Bristletooth Tang (Ctenochaetus truncatus), also known as Squaretail or Spotted Bristletooth Tang, can be found among reefs of the Indo-Pacific Ocean. They have a red or brown body and yellow ring around their eye, very closely resembling the Kole Tang, though C. truncatus adorns small yellow spots covering their body. They are herbivorous, feeding on macro algae and seaweed, and should have plenty of space to swim. They reach a maximum size of 6 inches, require a tank of at least 70 gallons, and should be kept with other fish of similar size and temperament. They are beneficial to reef aquariums as they help remove unwanted algae from corals or rocks.
