Betta fish are some of the most beautiful freshwater fish around. They come in many colors and have long, flowing tails. Relative to other fish, they require very little in order to survive and thrive. Whereas most fish may require elaborate setups with filters, skimmers, heaters and more to survive, the betta is typically fine in a small bowl without any equipment. No fish store would be complete without a collection of betta splendens ready and waiting for new homes. The betta has been referred to as the "gateway fish" because unsuspecting purchasers often start with small betta fish bowls and find themselves with full scale fish tanks before long!
