Common name: Yellowfin surgeonfish

General information

The Yellowfin Surgeonfish, Acanthurus xanthopterus, is a striking member of the Acanthuridae family, known for its vibrant coloration and active demeanor. This species is often admired for its deep blue to purple body contrasted with bright yellow fins, hence the common names. It is a large surgeonfish that can reach up to 70 cm in length in the wild, though in captivity, it typically grows to about 40 cm.

Care

Yellowfin Surgeonfish require a spacious aquarium to accommodate their size and active swimming habits. A minimum tank size of 500 liters is recommended. They are herbivores, so their diet should consist of marine algae, seaweed, and vegetable-based foods to maintain their health and coloration. It's important to provide plenty of live rock for grazing and hiding spots.

Reproduction

In the wild, Yellowfin Surgeonfish spawn in groups, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic before settling down and growing into juveniles. Reproduction in the home aquarium is rare and challenging.

Habitat

Yellowfin Surgeonfish are found in tropical and subtropical oceans, often in coral reefs, lagoons, and seaward reefs. They prefer clear waters with strong currents and are typically found at depths ranging from 1 to 100 meters. Their natural range extends across the Indo-Pacific region, from East Africa to the central Pacific Ocean.
