King British Tubifex Treats are suitable for all aquarium fish, plus turtles and terrapins. They are a natural river-dwelling worm, harvested, then freeze-dried immediately to retain flavour & nutritional value. We press the dried worms into one centimetre cubes, making them easier to feed to your fish. Tubifex is the type of food that a fish would choose to eat in the wild, and provides a welcome treat and protein-rich nutritional supplement to any fish. Free from artificial colours, flavours and preservatives. Feed sparingly 2 to 3 times per week as a complementary pet food treat. Promoting feeding as they would in the wild. Compliments a balanced diet. Easy to handle 1cm cubes. Can be stuck onto the glass inside the aquarium, making it fun to watch fish feeding. Available in 10g and 35g tubs.
