About
The double tail mutation causes the caudal peduncle to bifurcate, resulting in two distinct tail lobes and a shorter, deeper body than single-tail varieties. Double tail bettas also tend to have wider dorsal fins. While beautiful, the genetic trait is sometimes associated with swim bladder complications, so careful care is advised.
Care Guide
Water: 26-28°C, pH 6.0-7.5, soft to medium hardness — pristine water quality is especially important. Tank: minimum 20L, low-flow filtration; avoid strong currents that stress the unusual body shape. Feeding: carnivore — small betta pellets, bloodworm, daphnia; avoid overfeeding to prevent bloat. Behaviour: males aggressive to conspecifics — one per tank; tends to be slightly less active than other varieties. Compatibility: gentle community tank mates; not suitable with nippy fish.
