Hogfish are a reef-dwelling species of wrasse extremely popular in the modern aquarium trade. They possess a long, pig-like snout, that they use to search for crustaceans buried in the ocean floor and it is this behavior that gives the hogfish its name. Hogfish are also characterized by their rectangular shaped and laterally compressed bodies. All hogfish are protogynous hermaphrodites and are able to change sex over the course of their life. Most species also undergo drastic changes in coloration and body patterns when they reach adulthood, making the juveniles of the species significantly different in appearance to their adult counterparts. Hogfish are a vibrantly colored species of fish that come in dark shades of red, yellow, maroon, green, blue, brown and black. Their bodies are also often covered in intricate patterns and markings.
