The body of the surgeon fish is tall and flattened. Now, when it’s taken out of its environment and placed in ponds or fish tanks, it barely exceeds 15 centimeters. This fish can reach 30 centimeters in length when it’s in its natural habitat. The caudal fin of the surgeon fish is yellow, as is the edge of the pectoral fins, and depending on their age, the hue of the same will vary. In general, the lower strip joins the upper one, creating a sort of oval in which a much more penetrating and intense blue stands out. One of them (the upper one) goes from the caudal fin to the head, and passes through the eye, while the other (the lower one) extends in the direction of the pectoral fin. It shows a resplendent indigo blue throughout his body, in which two black bands also stand out. The Palette surgeon fish is characterized by its striking tones. Palette Surgeonfish: Main Characteristics 🐟 The Blue Surgeon changes color as he grows. Surgeon fish are called that because they have a sharp spine, hence their name as surgeons, since the surgeon doctors use a scalpel and this spine has a lot of edge.

The name Perciformes means «perch-shaped.» Perciforms, also called percomorphs (Percomorphi) or acanthoptera (Acanthopteri), include about 40% of all fish and are the largest order of vertebrates. The small mouth has a single row of sharp teeth, used to cut the algae it feeds on. Both the dorsal and anal fins are large, extending beyond body length. The distinctive feature of the family is a pair of spines, or scalpels, one on each side of the caudal peduncle, which are very dangerous stingers, which has given rise to its common name of surgeon fish. Most species are small with few exceptions usually don’t exceed 30 cm in length. Their bright and vivid colors make them very popular in aquarium. All members of this family are tropical marine fish that live between coral reefs.
