Suction cups for fixing to the glass of the aquarium.
The air pump is necessary for operation (not included!)
In the aquarium, the water is cleaned by the filter and enriched with oxygen, in the breeding tanks this is usually not possible. This is why we developed the Nido 4. By connecting an air pump you can continuously provide your young fish with clean water and fresh oxygen.
The two suction cups included allow easier fixing to the aquarium glass
