Acanthurus achilles

Acanthurus achilles, commonly known as the achilles tang or red-tail surgeonfish, is sensitive surgeonfish only suitable for experienced aquarists. It needs plenty of swimming space and clean water to thrive. It can be aggressive towards other fish, especially other tangs and food competitors, but once it is settled in the tank it will be the showpiece of the aquarium.

Like other tangs, it will eat meaty foods, but it's important it can graze on algae/seaweed the entire day to ensure it will stay healthy. So feed flakes/pellets multiple times a day and make sure there is always seaweed available.
