Powder Brown Tang
The Powder Brown Tang, also known as the Powder Brown Surgeonfish, Japan Surgeonfish, and White-faced Surgeonfish, has a brown body with a white mark on the cheek between the mouth and eyes. The pectoral, anal, and dorsal fins are dark brown with light blue highlights at the tip. The dorsal fin also has an orange stripe present. The tail is blue with a yellow vertical bar. Yellow striping runs along the body, against the anal and dorsal fins, forming a wishbone-shaped marking.
A 125 gallon or larger aquarium is necessary to provide plenty of swimming room. Keep only one Powder Brown Tang per tank. Use caution when housing with other Tangs or Surgeonfish. Similar shaped Tangs can be very aggressive towards each other.
Although Tangs will eat meaty foods along with algae, they may require a varied diet including spirulina, frozen foods, and algae wafers to maintain optimal health.

The Powder Brown Tang is a striking fish with beautiful coloration. After setting up a 150-gallon tank, it settled in well and started eating a mix of frozen foods and algae wafers. It’s active and peaceful when given enough space. Only keep one to avoid aggression.

Great addition to a reef tank. The white mark on its face is very noticeable. I feed it daily with spirulina and frozen shrimp. It’s not aggressive, but I make sure to keep it alone to avoid conflicts with other tangs.

The fish has a unique appearance with the blue and yellow markings. It’s active and clean, and it seems to enjoy the algae-based diet. I’ve had it for three months and it’s thriving in a 130-gallon tank.
