General information

The Hawaiian Bristletooth, scientifically known as Ctenochaetus hawaiiensis, is a distinctive and attractive marine fish popular among reef aquarium enthusiasts. It is known for its unique coloration, which transitions from a juvenile pattern of bold stripes to a more subdued, spotted appearance in adulthood. This species is part of the surgeonfish family and is recognized by its bristle-like teeth that are adapted for scraping algae from rocks and coral.

Care

Ctenochaetus hawaiiensis requires a spacious aquarium with plenty of live rock for grazing and hiding. It is essential to maintain high water quality and stable parameters to keep this fish healthy. A varied diet that includes marine algae and high-quality prepared foods will help maintain its vibrant coloration and overall well-being.

Reproduction

In the wild, Hawaiian Bristletooths are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare, but maintaining a group may increase the chances of observing reproductive behavior.

Habitat

Native to the Hawaiian Islands, Ctenochaetus hawaiiensis is typically found in clear, shallow waters around coral reefs. It is a hardy species that adapts well to life in captivity, provided its environmental needs are met.
