Once packet contains approx 3 tablespoons of freeze-dried bloodworm. Bloodworm are actually just mosquito larvae and they are a very nutritious fish food as they are high in protein. Feeding your fish bloodworm will improve their condition and in some fish induce breeding. As part of a healthy diet for your fish you should offer bloodworm twice a week as an alternative to flake food or micro-pellets. Some fish will only feed on bloodworm, or will prefer it to other foods.
The packets are re-sealable.
