Yellowbelly Blue Hippo Tang (Paracanthurus hepatus)

This is a regional color variant of the familiar Blue Hippo Tang, carrying a warm yellow underside beneath the same royal blue body and black "palette" markings — a variation seen in certain Indian Ocean populations rather than a separate species. Otherwise it's the same active, hardy fish behind the aquarium's most famous case of mistaken identity.

Care level: Moderate · Temperament: Semi-aggressive · Max size: ~12" · Min tank: 125+ gal · Diet: Herbivore, algae + herbivore pellets
