General Description: The Gold-Ring Spotted Bristletooth Tang, also known as the Square-tail Bristletooth Tang, is native to Africa and east toward Sri Lanka in the Indian Ocean. The species name, truncatus, aptly refers to their short and box-like tail (caudal) fin that lacks the pointed tips that are characteristic of all other species in the genus Ctenochaetus. Members of Ctenochaetus are among some of the most efficient algae grazers and this species is no exception. Juvenile Gold-ring spotted bristletooth tangs have a vibrant yellow body. As an adult, the body is more of a light purple color with some yellow hues. Charmingly at any age, the Gold-ring spotted bristletooth tang is covered in an abundance of tiny white polka dots and sports a vibrant yellow eye-ring. An adult Gold-ring spotted bristletooth tang can reach a size of approximately 6″. This smaller adult size makes it quite desirable among hobbyists.
Diet Requirements: In the wild tangs are primarily herbivorous. A diet largely consisting of algae-based foods is absolutely necessary to maintain optimal health, coloration, immune function, and reduce aggression. Vegetable based flake foods or frozen foods, that may also include spirulina algae, are excellent options. We also recommend offering dried seaweed on a rock or clip three times a week minimum. Bristletooth tangs will consume various other protein-based frozen foods.
Care Requirements: A minimum 90 gallon aquarium is ideal. Smaller specimens can be temporarily raised in smaller quarters as long as it is upgraded accordingly. This tang enjoys a variety of rock work to graze off of and crevices to take refuge, but should also be provided with some open swimming space. Typically, Ctenochaetus species are only semi-aggressive and territorial in nature toward members of its own genus, often behaving peacefully toward other tank-mates. However, if you want to house various types of tangs together, it is best to add them all at once, or closely together at the very least, for the best success. Recommended water conditions, 72-78° F, KH 8-12, pH 8.1-8.4, salinity 1.020-1.025.
