Overview:
The Xanthopterus Tang is a striking and large marine herbivore, known for its elongated body, dark gray to bluish coloration, and vibrant yellow pectoral fins. Its active swimming and bold appearance make it an eye-catching centerpiece in large reef or community aquariums.

Native to the Indo-Pacific, commonly found on coral reefs and lagoons from East Africa to Hawaii and the central Pacific.

Feeding:
Primarily herbivorous – thrives on marine algae, seaweed, and spirulina-based foods, supplemented with occasional meaty foods such as mysis shrimp for balanced nutrition and optimal coloration.

Tank Mates:
Best housed with peaceful to moderately semi-aggressive fish. Avoid overly aggressive or very small species to reduce stress and territorial disputes.

Aggression:
Moderately territorial – may defend feeding or swimming areas, particularly in smaller tanks, but generally peaceful in large, well-maintained aquariums.
