The palette surgeonfish

One of the most beautiful saltwater fish in the world is the palette surgeonfish which is also referred to as the regal blue tang, blue tang, and palette tang. The Indo-Pacific reefs contain and surround this species. This fish has spines that resemble weapons at the base of its tail, as is typical of surgeonfish. These oval-shaped fish have vivid blue bodies with accents of dark blue and yellow on their tails. These well-known aquarium fish are classified by the International Union for Conservation of Nature as a species of Least Concern (IUCN).

The name of this fish, Paracanthurus hepatus, accurately describes how it appears: It is painted in a design resembling a painter's pallet in stunning hues of blue, black, and yellow. The scapel-shaped tail is the source of the name "surgeonfish." It also goes by the name "regal blue tang."

Palette surgeonfish are found on coral reefs in the Indo-Pacific, including the Great Barrier Reef, just like the majority of the fish on our list of the most stunning saltwater fish in the world. Palette surgeonfish dwell in couples or small groups.
