Tank compatibility[edit]

Peaceful, but will be aggressive to similar species if space is limited. A specimen that feels threatened may attack your hand with the "saw" on their tail, so make sure not to spook them.


herbivorous, eats various macroalgae and microalgae, but may also be supplemented with meaty foods.

Feeding regime[edit]

Daily, at least 2 times.

Environment specifics[edit]

A grazer that may enjoy slightly cooler waters, as well as a large amount of rock for grazing.


Peaceful, and can be kept in groups housed in a suitably sized system. Can be observed "slapping" other fish with their peduncle spine to resolve territorial issues.


Covered in small black spots with three big spots on the caudal peduncle; similar to the Razor Surgeonfish, which is not as spotted. It also looks similar to the more commonly offered Mustard Tang, although it has a much longer snout than the Mustard Tang.
