Tangs make a great addition to any aquarium! Their Dori-like mannerisms make them enjoyable to watch, and they’re also beneficial to the aquarium because they eat algae. Tangs get along well with most other fish and are reef safe. For these reasons, they are a popular aquarium fish. KP Aquatics offers both Atlantic Blue tangs and Surgeon tangs. The Atlantic Blue tangs are bright yellow as juveniles and turn blue as they mature. Surgeon tangs maintain the same colors from juveniles to adult.
