Discus require exceptional nutrition to grow and develop vibrant coloration. This is especially true when conditioning breeding pairs and raising young fish. New Life Spectrum Naturox Discus sinking pellet food is packed with high-quality, nutrient-dense ingredients that provide the right balance of protein, fat and fiber along with essential vitamins and minerals. Whole Antarctic krill and squid supply the proteins and amino acids needed for growth and energy. Ulva seaweed, Chlorella, Spirulina and kelp contain color-enhancing carotenoids and anti-oxidants. Garlic is added as a feeding stimulant and its anti-parasite effects. Ginger boosts the immune system for improved disease resistance. Naturox Discus pellets use a natural anti-oxidant to maintain freshness without the need for controversial ethoxyquin preservatives. The pellets contain no artificial preservatives, colors or hormonal color stimulants.
