The blue tang — Dory from Finding Nemo — is one of the most recognizable marine fish with its vivid royal blue body, black palette marking, and yellow tail. While stunning, they grow large (up to 12 inches), are highly susceptible to ich, and need tanks of 75+ gallons. They are not beginner fish despite their popularity following the movies.
