The Thompson's Tang (Acanthurus tompsoni) is a plankton-eating Tang. This fish occurs from East Africa to Hawaii. Depending on the waters it came from, it will be either a uniformly blue-grey with a white tail, or brownish-purple with pale yellow accents highlighting its fins and tail. In Hawaiian waters its tail fin is dark, being the same color as the body. Everywhere else, however, its tail fin is bright white.
The Thompson's Tang requires a large aquarium (250+ gallons) with strong water movement and aeration. Although Tangs will eat meaty foods along with the other tank mates, it is important that they are offered plenty of marine-based seaweed and algae at least 3 times a week. This will strengthen their immune system, reduce aggression, and improve their overall health. It's best to soak the seaweed or algae in a vitamin supplement such as S.E.L.C.O Boost prior to feeding.
Acclimate all new fish to ensure a smooth transition to its new aquarium.
