Common surgeon are strictly marine and can be found in tropical and sub-tropical coastal regions where temperatures are between 24 and 26 °C. They congregate near Pocillopora eydouxi, a type of coral with branching extensions, which serve as a protective hiding place when threatened. Reefs provide plant material, such as algae, necessary as food for common surgeon. Common surgeon remain at epipelagic depths between 2 and 40 m. ( "Palette surgeonfish", 2009; Froese and Pauly, 1991; Myers, 1991)

Due to the small shape of their mouth, surgeonfish can easily pick and remove algae from uneven surfaces. Aggregations of common surgeon eat the fast growing algae from sponges in their habitat. This benefits the sponges and indirectly preserves habitat for species dependent on the steady growth of sponges.
Where do surgeon fish live?
Common surgeon, Paracanthurus hepatus, are strictly marine fish that typically inhabit tropical coral reefs in waters with a strong current.

Generally, common surgeon range between 30° north and south latitude and 32° east to 170° west longitude in the Indian and Pacific Oceans. Individuals found in other areas are presumed to have been released from aquaria. ( "Palette surgeonfish", 2009; Froese and Pauly, 1991; Myers, 1991; "Blue Tang", 1999)

Meet the Real-Life "Dory"
Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels.
Appearance
Surprisingly, the blue tang isn't always blue. An adult regal blue tang is a flat-bodied, round-shaped fish with a royal blue body, black "palette" design, and a yellow tail. It reaches 30 cm (12 inches) in length and weighs around 600 g (1.3 lbs), with males typically growing larger than females.
Diet and Reproduction
Juvenile blue tangs eat plankton. Adults are omnivorous, feeding on some plankton as well as algae. Blue tangs are important for reef health because they eat the algae that could otherwise cover the coral.
Sword Fights and Playing Dead
Blue tang fins contain spines sharp enough to be comparable to a surgeon's scalpel. There are nine dorsal spines, 26 to 28 soft dorsal rays, three anal spines, and 24 to 26 soft anal rays. Humans or predators foolish enough to grab a regal blue tang can expect a painful and sometimes venomous stab .
Ciguatera Poisoning Risk
Eating a blue tang or any reef fish carries the risk of ciguatera poisoning. Ciguatera is a type of food poisoning caused by ciguatoxin and maitotoxin. The toxins are produced by a small organism, Gambierdiscus toxicus, which is eaten by herbivorous and omnivorous fish (such as tangs), which in turn may be eaten by carnivorous fish.
Conservation Status
The regal blue tang is not endangered, classified as "least concern" by the IUCN. However, the species faces serious threats from habitat destruction of coral reefs, exploitation for the aquarium trade, and use as bait for fishing. To catch fish for aquaria, the fish are stunned with cyanide, which also damages the reef.
