era O-Nip Nature is the dye-free and preservative-free candy based on carefully prepared tablets, which can easily be stuck onto the aquarium glass by pressing them with your finger. This makes it very easy to observe the fish, even the shy ones, while they are eating. The sticking tablets are characterised by their high natural animal content: in addition to mosquito larvae and Tubifex, sera O-Nip Nature also contains 7% krill. Thanks to these ingredients, the tablets are very rich in nutrients and very valuable for a natural diet. The natural ingredients and the high content of easily digestible protein promote healthy development, good appearance and natural behaviour.
