Sumida aquarium, Tokyo 1

This tank is located at Sumida aquarium and makes use of large Java fern and bolbitis to good effect. Anubias barteri are used at the bottom near the substrate, as they can grow in shade. Using mostly slower growth epiphytes makes for easier maintenance for large sized public aquariums. The water outlet pipes placed near the top provides surface agitation and gaseous exchange - which are important even in large tanks.
