The fish tank in Finding Nemo, located in Philip Sherman's Sydney dental office, is a bustling, tropical saltwater aquarium filled with fake coral, a Tiki hut, a pirate ship, a skull, and a "volcano" (Mount Wannahockaloogie). It houses the "Tank Gang" and is later upgraded with an algae-removing AquaScum 2003 laser system.

Key details about the tank include:

• Decor: A bubble-blowing treasure chest, a scuba diver puppet, a "volcano" (Mount Wannahockaloogie), a sunken ship with a mermaid figurehead, a pirate skull, fake seaweed, a Tiki heads trio, and a "Didn't Brush" sign.

• Tank Gang: The inhabitants include Gill (A scarred Moorish idol), Peach (starfish), Bloat (porcupine puffer), Deb (and Flo) (humbug damselfish), Gurgle (royal gramma), Bubbles (yellow tang), and Jacques (cleaner shrimp).

• Features: It serves as a "clean" environment (due to Jacques and the filter) that is later threatened by the addition of the AquaScum 2003, which eliminates manual cleaning.

• Design & Purpose: It is designed to be a calming feature for patients, though it acts as a "prison" to the fish, who often dream of escaping.
