Siamese fighting fish (Betta splendens), also known as Bettas, can be found in the standing waters of canals, rice paddies and floodplains. The waters tend to be rich in tannins released by fallen leaves. To simulate the conditions of their natural environments, special water conditioners have been produced as supplements to aquarium water. Browse our selection of manufactured products as well as all natural products that will help enrich your aquarium water with tannins.
Tannin rich waters are believed to have anti-fungal and antibacterial properties. While the validity of these claims remain to be seen, one thing is clear, Betta splendens come from a tannin-rich habitat and simulating an environment, for which the species is adapted, makes sense.
