A living cartoon aquarium. Colourful fish wander among layered textured rocks and swaying seaweed, only the underside of a gently bobbing boat is visible at the top edge, with a fishing line descending above freely swimming fish and three freely roaming schools of tiny silver, gold and turquoise fish that scatter when a member is eaten, a smaller-headed octopus swims up and down, and a red crab climbs the rock piles and catches nearby ordinary fish with its claws. Big fish hunt the tiny school; the Nemo team is protected. The Finding Nemo tank gang swims among the other fish. Jacques roams the rocks, cleans visiting fish, and scrubs the front glass with a sponge roughly every fifteen minutes. Aquarium gravel, a terracotta cave, a bubble stone, a corner filter, a large volcano against the back wall that erupts on the local hour, and glass reflections complete the tank. Automatic day and night lighting follows the device’s local time, with two blue-violet overhead bulbs and two warm tiki torches lighting the darker night water from below.
