Gill is the maverick of the dentist’s office fish tank. He is the leader of an eclectic gang of tropical fish, who hang on his every word and are drawn to his magnetic personality. This tough, scarred, one-finned fish was raised in the ocean, but was taken at a young age to live in a tank. Surrounded by fish who have spent their entire lives in “the box,” Gill alone feels the pull to be free. Though he dreams of one day breaking out and returning to the ocean, his failed escape attempts have
broken his spirit. With Nemo's arrival to the tank, Gill is inspired again to find a way back to the sea.
