Powder Blue Tang Fish

The Powder Blue Tang, *Acanthurus leucosternon*, is a highly sought-after and visually stunning surgeonfish known for its vibrant coloration. Its body is a brilliant powder blue, contrasting sharply with a bright yellow dorsal fin and a white chest. A black band runs across its eyes, adding to its striking appearance.

A minimum tank size of 125 gallons is recommended for a single Powder Blue Tang to provide ample swimming space and reduce stress. They are active swimmers and require a mature aquarium with plenty of live rock for grazing on algae and providing hiding places. While generally considered reef safe with caution, they may occasionally nip at certain corals or invertebrates, especially if not well-fed.

Powder Blue Tangs are primarily herbivores and require a diet rich in marine algae. Offer a variety of foods including high-quality marine flake and pellet foods, dried seaweed (nori) tied to a rock or clip, and occasional offerings of mysis shrimp or other meaty foods. Providing a constant supply of algae is crucial for their health and to prevent them from picking at corals. They are susceptible to Ich and other parasitic infections, so maintaining excellent water quality is essential.
