Tetra has been revolutionizing and improving fish nutrition since the company's birth in Germany in 1951. Since that time, Tetra has developed one of the most comprehensive bodies of flake fish food knowledge in the world. A full team of biologists, chemists, and nutritionists continually study and discover what keeps fish thriving and living long, healthy lives. This high quality, large sinking wafer is ideal for Plecostomus and excellent for all bottom feeding fish such as catfish and loaches. The food provides nutritious, fiber rich variety to help keep freshwater ornamentals in peak condition. Contains the patented health enhancing ProCare blend from TetraMin and does not cloud water when used as directed. Tetra formulas feature micro milled, exotic, high-protein fish meal as a core ingredient--making them pure and digestible with fewer colorants. This leads to less waste and a cleaner, clearer aquarium. Tetra understands that every fish is unique. For this reason, they have created a full menu of food to help meet the needs of every fish; from bottom feeders to top-feeders and small Bettas to Large Cichlids.
