Paracanthurus hepatus

Blue Tang, Paracanthurus hepatus is an planktivore during the Juvenile stage, and Omnivorous in the adult stage.

Blue tangs are prone to easily contracting ich and is very susceptible to lateral line and fine erosion - especially when kept in smaller aquariums. Even the smallest sizes of the Blue Hippo Tang require large amounts of swimming space and should be in a tank no less than 100 gallons as tiny juveniles due to their need to swim in the open.
