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 while they are eating. The high amount of quality protein sources such as bloodworms, Krill and Tubifex makes these tablets particularly tasty, wholesome and valuable for appropriate nutrition. Quality ingredients as well as a high, easily digestible protein support healthy development, great color and natural behavior.
