Some famous cartoon fish include Nemo and Dory from "Finding Nemo," Flounder from "The Little Mermaid," and Klaus from "American Dad." The first three of these fish are family-friendly Disney characters, while Klaus is associated with the ribald comedy of Seth MacFarlane.

Nemo the clownfish is one of the main characters in Disney-Pixar's 2003 computer animated film, "Finding Nemo." Dory, a blue tang fish, has a smaller role in the same film. The movie contains numerous other piscine characters, including Nemo's father, Marlin. A traditionally animated movie, "The Little Mermaid" also contains many sea animal characters. Flounder, a yellow and blue striped fish of indeterminate species, is best friends with the protagonist, Ariel.

Klaus Heissler is a talking goldfish on the animated television show "American Dad." Originally a human whose consciousness was transferred into the body of a fish, Klaus lives in a fish bowl as a family pet. He retains a human level of intelligence and a strong attraction to human females, which is played to humorous effect.
