TetraPond Aquarium & Pond Supplies
Tetra is synonymous with ornamental fish keeping thanks to Dr. Ulrich Baensch. He founded Tetra in Melle, Germany 50 years ago and pioneered the development of flake fish foods. Tetra now manufactures hundreds of products and publishes books for aquarium fish keeping, reptile and amphibian keeping and water gardening. Tetra’s German headquarters act as the company’s research and manufacturing center for the Tetra fish foods, nutrition products and water conditioners. We carry many popular TetraPond products including algae control solutions, food, medicine, water test kits and more.
