Acanthurus nigrofuscus, also known as the Lavender tang, Brown Tang, or Spot-Cheeked Surgeonfish, is a tang from the Indo-Pacific and Hawaii. It commonly makes its way into the aquarium trade. It grows to 36 cm in length. Recently, a huge bacterium discovered in its intestine, Epulopiscium fishelsoni,[1][2] has been found to grow as large as 600 by 80 μm, a little smaller than a printed hyphen, which controls the pH of its host's gut, thereby influencing its host's ability to digest food and absorb nutrients.

Diet[edit]

The Lavender Tang is an herbivore that grazes primarily on benthic algae. In captivity, they will also feed on animal matter such as brine shrimp and mysis shrimp.
