Aquarium system for positioning fishes and aquatic microbes e.g. fresh water dwarf shrimp, has closed system with upper container region filled with gas i.e. air, and container formed with watertight lockable opening
The system (1) has a container (2) made of a transparent material and accommodates water. An aquarium forms a closed system, and a lower container region (3) of the closed system is filled with the water. An upper container region (4) of the closed system is filled with gas i.e. air, and a watertight lockable opening (13) is provided in the container. A substrate of the system forms a subsurface for algae and/or bacteria, and consists of a fibrous material i.e. coconut fibers.
