The Yellow Belly Hippo Tang (Paracanthurus hepatus var.) is a variant of the Blue Hippo Tang (Paracanthurus hepatus) found in the Red Sea. It is distinguished from the standard Blue Hippo Tang by its yellow belly coloration, which replaces the blue coloration found on the standard variety. This variant is highly sought after by marine aquarists.

Physical Description

The Yellow Belly Hippo Tang has a laterally compressed, oval-shaped body. The body is a vivid royal blue with a black palette-shaped mark on the side and a yellow caudal fin. The belly is yellow, which distinguishes it from the standard Blue Hippo Tang. The dorsal fin has 9 spines and 19-20 soft rays while the anal fin has 3 spines and 18-19 soft rays. This species reaches a maximum total length of 31 cm (12.2 in).

Distribution and Habitat

Diet and Feeding

The Yellow Belly Hippo Tang is omnivorous, feeding primarily on plankton and marine algae in the wild. In captivity, it should be offered a varied diet including marine algae, spirulina, mysis shrimp, and high-quality marine fish preparations.

Aquarium Care

The Yellow Belly Hippo Tang requires a well-established aquarium of at least 75 gallons with stable water conditions and abundant live rock. It is generally peaceful but may become territorial toward other tangs. It is prone to marine ich and requires excellent water quality. Generally considered reef-safe.
