What is what kind of fish is oscar in shark tale?

In the animated movie "Shark Tale," Oscar is a fictional character who is a cleaner wrasse fish. Cleaner wrasses are small fish that are known for their symbiotic relationship with larger marine creatures, such as sharks. They feed on parasites and dead skin cells, providing a cleaning service for their clients in exchange for protection.

While Oscar in "Shark Tale" is a cleaner wrasse, the movie takes creative liberties with the character, depicting him as a fast-talking, ambitious fish who gets caught up in a case of mistaken identity and ends up rubbing shoulders with the mafia-like shark underworld. Oscar is voiced by actor Will Smith in the film.
