Squaretail Bristletooth Tang
One of the most vibrantly-colored of its genus when young, this fish features a vibrant yellow body. The species is named truncatus due to its short tail fin, which lacks the pointed tips common in other members of the genus Ctheochaetus.
Adult Squaretail Bristletooth Tangs have a brown to orange body with pale blue to bright yellow spots on the head, body, and base of the dorsal fin. The outer part of the eye is ringed in bright yellow.
Equipped with a protruding mouth and bristle-like teeth that can move individually, this fish uses them to sift, sort, and scrape for food.

The fish is very colorful and active. It has bright yellow spots and a distinct yellow eye ring. I’ve kept it in a 75-gallon tank with other tangs, but it does show aggression toward similar species. Needs plenty of space and a well-maintained environment.
Stewart Morgan –
Beautiful fish with vivid colors. The eye ring and body spots stand out. It’s active and helps keep the tank clean by scraping algae. I had to separate it from another tang after a few weeks due to fighting.
Lily Ogden –
Looks impressive in the tank. The coloration is striking, especially when the light hits the yellow spots. However, it’s not suitable for smaller tanks or mixed with other tangs. Needs a large, stable setup.
