🐟 Double Tail Betta Fish (Betta splendens)
Solitary Display Fish • Striking Split Two-Lobed Tail • Choose a Straight Spine and Feed Lightly
📋 The Double Tail Betta has a caudal fin split into two symmetrical lobes, along with a broader dorsal fin to match. It's an eye-catching, popular variety that comes in vibrant colour patterns, and many individuals live full, healthy lives with good care.
The double tail gene that splits the tail also shortens and compresses the body, reducing the space available for the swim bladder. That makes Double Tails more prone to swim bladder trouble, such as difficulty staying upright, floating nose-down, or sinking, than most other betta varieties, so the secret to a great Double Tail is choosing well and feeding lightly. A great Double Tail has a visibly straight spine and a graceful, balanced fin spread. Small portions help, since a full digestive tract can press against an already-compressed swim bladder.
As with all bettas, keep Double Tails solitary, since males are territorial.
