From the manufacturer:
Omega One® Bloodworms are genuine bloodworms, not mosquito larvae, which means their color enhancing ability is superb. Their high protein content makes them particularly effective as a conditioning food for breeding fish. These premium, bacteria-free bloodworms are an excellent treat for many freshwater and saltwater species.
GREAT FOR: Rainbow Fish, Discus, Angel Fish, many types of African Cichlids, Triggers, Blennies, Saltwater Angels, and many other species.
All Omega One® Frozen Treats undergo an 8-Step Cleansing Process prior to packaging to ensure purity. UV Sterilization also eliminates the risk of parasites or bacteria.
