Tetra has been revolutionizing and improving fish nutrition since the companys 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. TetraColor Tropical Flakes work to promote the natural pink to orange-red colors of tropical fish.

A precise dose of select vitamins and nutrients support immune system health while Omega-3 fatty acids promote energy and growth. For best results, feed TetraColor Tropical Flakes in conjunction with TetraMin Flakes for a staple diet. Tetra formulas feature micro milled, exotic, high-protein fish meal as a core ingredientmaking them pure and digestible with fewer colorants. This leads to less waste and a cleaner, clearer aquarium.
