View Marine Fish Compatibility Chart

The Acanthurus xanthopterus, commonly known as the Yellowfin Surgeonfish, is a medium to large-sized marine fish celebrated for its distinctive features and vibrant colors. Reaching up to 15-20 inches in length, this species has a robust, oval-shaped body that is laterally compressed. The overall coloration of the body is a gradient of blue to gray, often with a slight iridescence that catches the light beautifully.

One of the most striking characteristics of the Yellowfin Surgeonfish is its bright yellow pectoral fins, which contrast sharply with the more subdued body color. The caudal fin is often edged with white or blue, adding to its visual appeal. Additionally, a sharp, retractable spine or "scalpel" is located on each side of the tail base, which is typical of surgeonfish and used for defense.

Native to the warm waters of the Indo-Pacific region, including the Great Barrier Reef and Hawaiian Islands, Acanthurus xanthopterus inhabits coral reefs and lagoons, where it grazes on algae and detritus. This species is known for its active swimming behavior and can often be seen in small schools or solitary, foraging among the corals and rocky substrates.

Yellowfin Surgeonfish are popular in the aquarium trade due to their stunning appearance and dynamic presence, although they require ample swimming space and a well-maintained environment. Their diet in captivity typically includes a variety of marine algae, vegetable matter, and high-quality prepared foods to ensure their health and vibrant coloration.

Tang's can typically get along if they are not the same species and/or ample living space is provided given they are introduced at the appropriate size & time. The powder blue tang can be aggressive, especially when larger so often times it is the last fish that a reef keeper will add.
