A natural food in the form of chunks of freeze-dried Tubifex worms, for omnivorous and carnivorous fish. Tubifex worms are very eagerly eaten by fish and aquatic turtles, and are a source of easily-assimilable protein. As fresh or frozen Tubifex worms can be the source of dangerous pathogens, we used a freeze-drying technique which effectively eliminates all pathogens while retaining delicate vitamins, unsaturated fatty acids, proteins, and other valuable substances. This makes TUBI CUBI an exceptional natural food for ornamental fish. You can use the worms in their dried form or soak them in water beforehand. We recommend other freeze-dried products from our range: RED MICO and FD BRINE SHRIMP.
