Hobby spawning box NIDO 5 is a spawning box with connection for an air pump for better keeping and rearing conditions. The tank can be divided into three sections. Your fish cannot survive without oxygen. In the aquarium, the water gets constantly cleaned by filters and enriched with oxygen. In spawning and breeding tanks this is usually not possible. This is why Hobby developed NIDO 5. By connecting a membrane pump (air pump) you may constantly supply your young fish with fresh oxygen. And thanks to the air lifting function, your young also get a steady supply of fresh and clean water, which supports their well-being and growth. Additionally, Hobby NIDO 5 sticks out through additional innovative ideas - for example the two feeding openings integrated into the lid. This allows for a targeted feeding without the need to lift the lid. Hobby NIDO 5 can be sub-devided into 3 separate chambers. This way you may host several expectant female fish at the same time.Hobby Fish Breeder NIDO 5+
