Dory is a Regal Blue Tang, Paracanthurus Hepatus of the family Acanthuridae. Babies eat plankton, but adults are omnivores and will also graze on algae. Primarily this is a bait fish (sorry!)but are popular for the aquarium trade- you can be badly cut by the caudal spine, or thrashing of the tail, posing a risk of infection.
