Sera O-Nip is the delicacy consisting of carefully manufactured tablets that can be attached to the aquarium glass by slight finger pressure. This allows for watching even shy fish excellently while they are eating. The high amount of food animals such as bloodworms, Krill and Tubifex makes the tablets particularly tasty, wholesome and valuable for appropriate nutrition. Valuable ingredients as well as a high, easily digestible protein amount support healthy development, splendid appearance and natural behavior.
