THE Betta, scientifically Betta splendens, aka the Siamese Fighting Fish, is likely only second to the common goldfish as the most commonly kept pet-fish; and rightly so. Bettas are hardwired tough, easily able to survive being abruptly moved, having a wide range of tolerance for variable water quality, a ready acceptance of foods, and innate resistance to most diseases. Despite these positive human-use traits, way too many Betta splendens meet their fate unduly and too soon. What they do need is simple: steadily warm (tropical) system conditions with either provision of simple filtration, or steady change out of water with new that is suitable; and adequate nutrition. In this small book the simple requirements of this species captive care will be revealed in a pleasing manner; as it is my express desire that you too become a successful Betta keeper.
