Powder Blue Tang

The Powder Blue Tang, Acanthurus leucosternon, also known as the Powder Blue Surgeonfish, has a disk shaped body, featuring a bright light blue body with a yellow dorsal fin and caudal peduncle, and a darker face outlined in white. Making it a real eye catcher in your aquarium. The Powder Blue Tang also has a scalpel at the base of their tail fin which is very sharp and is used by the Tang for protection from predators,  as well as a way of establishing itself with tank mates. Caution should be used when handling Surgeonfish as a cut from its scalpel can cause discoloration and swelling of the skin with a high risk of infection.
The Powder Blue Tang can grow to be about 9" and requires a tank no less than 125 gallons as a fully matured adult. Lush natural algae growth in the tank is suggested in order for the Tang to be able to graze upon in between meals. They may also jump out of an open aquarium, so be sure to have a tightly fitting lid.
Being a peaceful fish in nature, it will get along with most other peaceful tank mates, though it will aggressively defend its territory against other Surgeonfish and Tangs, and is best kept individually.
