King British Bloodworm Treats are suitable for all aquarium fish, turtles & terrapins.  Bloodworms are insect larvae, freeze dried immediately after harvest to retain flavour & nutritional value.  Their name comes from their natural red colour, and they are the type of food that freshwater fish would choose to eat in the wild.  They are rich in iron and protein, and promote excellent colour & condition.  A welcome addition to any diet.
