Powder Brown Tang

Greek Name: (Acanthurus japonicus)



The Powder Brown Tang, also called the Powder Brown Surgeonfish, Japan Surgeonfish as well as White-faced Surgeonfish, has a brown body that has a white mark across the face between the eyes and mouth. The pectoral and anal as well as dorsal fins have dark brown and have lighter blue highlights near the point. The dorsal fin has an orange stripe. Tail fins are blue and have an orange vertical bar. The yellow stripe runs across the body, and against the dorsal and anal fins, creating a wishbone mark.

A 125-gallon or larger aquarium is essential to ensure ample swimming space. Only keep 1 Powder Brown Tang per tank. Take care when housing different Tangs and Surgeonfish. Similar in shape Tangs can be extremely hostile towards one another.

While Tangs are known to eat meaty food alongside divers in their aquarium, it’s crucial that they receive lots of marine-based seaweed and algae. This can boost the immune system of Tangs, decrease aggression, and boost their overall health. Provide dried seaweed that is tied to a rock, or an organic clip and feed them at least three times a week. Sea Veggies, Seaweed Salad, and Ocean Nutrition are all ideal products and are extremely user-friendly.
