Tannin Aquatics begins with a lifelong love of all things aquatic and a vision to provide the most natural fishing environment for freshwater tropical fish. The name "tannin" was chosen because it is the substance extracted from leaves and wood that gives life to tropical rivers and streams and has a beautiful brown color that you will find so alluring. Dark waters, tangled roots and colorful leaves found along the shores of tropical "black water" rivers and streams provide an irresistible theme for them to replicate in aquariums. Their slogan "leaf, wood, water, life" perfectly sums up their point of view and mission. Headquartered in Los Angeles, California, Tannin Aquatics is about providing other amateurs with something to get excited about. Whether it's unusual aquascaping materials, hard-to-find "small-batch" fish food with local aficionados, specialized aquarium hardware, substrate additives or fish-raising equipment -- everything they sell is what they use and believe.
