Achilles Tang

Achilles Tang

Acanthurus achilles

The Achilles Tang is a stunning but demanding fish — its dark body is dramatically punctuated by a vivid teardrop-shaped orange-red blotch near the tail. Found in high-flow, oxygen-rich Pacific reef environments, it requires pristine water quality, strong circulation, and a very large tank (150+ gallons). Considered an expert-level fish prone to ich and stress.
