The global market leader in fish food for home aquariums. Tetra invented flake food for ornamental fish in the 1950s and still dominates a niche most people never think about.
Founded by Dr. Ulrich Baensch in Melle, Germany, Tetra turned a hobbyist’s problem — keeping exotic fish alive at home — into a category it has led for over half a century. A textbook hidden champion: absolute dominance in a market nobody talks about.
