Thompson's Tang

Acanthurus thompsoni. The Thompson's Surgeonfish is a stunning and very rare tang. Thompson's Surgeonfish have a mostly dark blue body with black markings.

Thompson's Surgeonfish reach a maximum adult size of around 10 inches and need to be kept in tanks that are at least 240 gallons in size. Thompson's Surgeonfish are peaceful fish and shouldn't bother other fish, coral or inverts in your tank. For this reason Thompson's Surgeonfish are great additions to reef tanks. Thompson's Surgeonfish can be somewhat aggressive to other tangs, especially other Acanthurus tangs. To help lower aggression between tang, you should try to introduce them all at the same time in a very large tank. Tangs will also be less aggressive when they are given a constant supply of algae to graze on.
