Blue Tang (Paracanthurus Hepatus) is a species of Indo-Pacific surgeonfish. A popular fish in marine aquaria, it is the only member of the genus Paracanthurus. A number of common names are attributed to the species, Including Regal Tang, Palette Surgeonfish, Blue Tang, Royal Blue Tang, Hippo Tang, Flagtail Surgeonfish, Pacific Regal Blue Tang, and Blue Surgeonfish.

Regal Blue Tangs  are identified by their bright blue coloring, oval bodies and yellow, flag-shaped tails. Adults have a narrow line of dark blue along their dorsal fin that curves back at the tail. This fish is rather flat, like a pancake, with a circular body shape, a pointed snout-like nose, and small scales. These fish have a sharp and venomous spine at the base of their caudal fin, or tail fin, to protect themselves from predators. The caudal spine contains a toxin that can cause severe pain, to small predators as well as humans.

Regardless of common name, Paracanthurus Hepatus is equal parts beauty and peacefulness that suits almost any large community marine aquarium.

Blue Tang likes to hide well among living stones. However, this active fish also loves to swim. Blue Tangs should be kept in an aquarium of at least 180 gallons. 

Though peaceful towards most tankmates, the Pacific Blue will become aggressive towards other fish of its own species. To keep multiple specimens, introduce the entire lot at once into a larger marine system.

Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen the Blue Tang's immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least three times per week. Ensure highest water quality and a varied diet, rich in nutritious marine-base vegetables to keep your Blue Tang in optimal health.
