The White Cheek Tang, also known as Acanthurus nigricans, is a beautiful and popular saltwater fish species among aquarium enthusiasts. They are native to the Indo-Pacific region and are characterized by their stunning white cheeks, yellowish body, and black vertical stripes.


These fish can grow up to 10 inches in length, so a large aquarium of at least 125 gallons is necessary to provide them with ample swimming space. White Cheek Tangs are generally peaceful but can become aggressive towards other tangs if kept in small tanks. It's best to keep them with other peaceful fish species that are not similar in appearance.


White Cheek Tangs are herbivores and should be fed a varied diet of high-quality algae-based flakes, pellets, and frozen foods. It's important to offer them plenty of vegetable matter, such as spirulina, seaweed, and algae, to maintain their health and well-being.


These fish have a unique trait of being able to change color depending on their mood and surroundings. When they are stressed, their stripes may become more pronounced, while their white cheeks may become less visible. They also have a sharp spine at the base of their tail, which they use for self-defense.
