Bristletooth Tomini Tang
The Bristletooth Tomini Tang, also known as the Tomini Surgeonfish, is tan combined with yellow, blue, and white highlights as a juvenile. When mature, the body color solidifies, the tail becomes blue, and the dorsal and anal fins are tipped with a golden-yellow hue. The area above the eyes has small golden flecks while sporting a golden half circle beneath.
A 70 gallon or larger aquarium is necessary to provide plenty of swimming room. It is aggressive towards other Tangs, but peaceful with other fish.
Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed as a regular part of their diet.

The fish has a beautiful color change from juvenile to adult. It’s active and shows good health with proper algae feeding. I keep it in a 90-gallon tank with peaceful species. It’s not aggressive with non-Tang fish, which is a relief.

Great coloration and active swimming. I feed it a mix of algae wafers and meaty foods. It seems to thrive in a well-maintained marine setup. Needs space, but worth it for the appearance.

The golden markings are striking. After a few months, the coloration stabilized as expected. I noticed it’s more relaxed when given plenty of seaweed. Good for a visually appealing tank.
