The Giant Short Tail Betta (Betta anabatoides or selectively bred Betta splendens giant variant, depending on strain) is a large, robust labyrinth fish admired for its size and unique finnage. Unlike long-finned bettas, the short tail (plakat-type) has stronger, more compact fins, making it less prone to tearing and easier to care for. Giants can grow 3–5 inches long, requiring larger aquariums than standard bettas, ideally 10–20 gallons for a single fish. They are territorial, especially males, so they are best kept alone or with carefully chosen peaceful tankmates that won’t nip fins. A well-planted tank with hiding spots, gentle filtration, and a secure lid (bettas are jumpers) is essential. They prefer warm, slightly acidic to neutral water, and their diet should consist of high-quality betta pellets, frozen or live foods such as bloodworms, brine shrimp, and daphnia. With good care, Giant Short Tail Bettas can live 3–5 years and make an impressive centerpiece fish.
