Tropical Mini Wafers Mix is a specialized multi-ingredient sinking wafer blend designed specifically for omnivorous bottom feeding fish and crustaceans. Mini Wafers Mix is created by Tropical with the intention of imitating the taste, texture, and diet commonly consumed by bottom-feeders in the wild, with each wafer colour-coded. Red wafers are the source of natural astaxanthin and beta-glucan, and help stimulate your pet's immune system. Green wafers contain spirulina and fibres which help regulate proper digestion and encourage appetites. These wafers do not dissolve in water, but instead keep their texture as they fall within reach of bottom-feeders and crustaceans, making feeding much easier for these animals.
