Our line of Sinking Wafers for bottom feeders, algae eaters, and freshwater shrimps are nutritionally complete and scientifically formulated to provide all proteins, vitamins, and minerals necessary for healthy growth and development. They have thin edges, making them easy for fish to nibble and the shape and size incite natural feeding behavior. The Wafers are made from the finest ingredients, are highly stable and do not break down quickly or cloud the water. They contain stabilized Vitamin C and other immune boosters and are low in phosphorus and ash.
