Who would have thought that one day we would be feeding our fish bristleworms but the new Aquathrive fish food from Reef Nutrition does just that. Beside fish meal the main ingredient of Aquathrive is polychaetes, of which bristleworms are a member. The crude protein content is up there around 46% and it has no preservatives. Feeding polychaetes is a more sustainable way of providing protein in fish food and exacting malicious revenge at the same time. The new food is available from Reed Mariculture/Reef Nutrition.
