13 | Video - Unicornfish The Acanthuridae family contains the fish that are known as Surgeonfish, Tangs, Unicornfish, and doctorfish. The popular 'unicornfish' are from the Naso genus, and are called the unicornfish because some of the species have a horn-like projection on the forehead like the one in the video. The name "surgeonfish" is derived from their possessing erectable razor sharp spines called 'scalpels' at the base of their bodies just in front of the tail fin. These spines or scalpels are very sharp and can cut like a knife. They have oval bodies that are very compressed laterally and small mouths adapted for nibbling and scraping small organisms from the rocks and coral. Most varieties of Surgeonfish can be kept together, but sometimes they can be territorial. It is best to add all your specimens at the same time or rearrange the rockwork when adding a new species to an aquarium already containing a resident surgeonfish. Read about each species to learn about its size, adaptibility, beharior, diet, and especially compatibility with its own species as well as any other species.
