Pettex Sinking Pellets are a high quality fish food suitable for all cold water bottom feeding fish, including Sterlets, Catfish, Tench and many other species. Our highly digestible and balanced formulation gives your fish the healthy diet they require. Designed for all bottom feeders who may not receive food when normal floating pellets or sticks are used, Pettex Sinking Pellets provide a balanced range of minerals, vitamins, fibre, and a high protein content for fast growth. Our balanced formula avoids the need for over feeding and so reduces possible water pollution. nbsp nbsp
