Hikari Tropical Sinking Wafers provide a complete and balanced diet, ideal for bottom feeding fish such as Corydoras Catfish, Loaches and other small bottom dwellers. Sinking Wafers have an easy to digest, low waste formula and have been designed to boost the immune system of your fish. Sinking Wafers have a unique shape designed by Hikari specifically for the feeding requirements of bottom feeders which have downward facing mouths and gulp their food. The Wafers are packed full of healthy nutrition and offer an extremely flavourful diet, containing premium-grade fish meal, silkworm and krill. The addition of spirulina algae ensures your fish always look their best. Feeding Directions:Feed up to twice a day. Feed the amount your fish will completely consume in 20 minutes. Care should be taken to avoid over-feeding and always remove any uneaten food after feeding to avoid water clouding.
