Double Tail (DT) Betta
The Double Tail (DT) Betta is a type of Siamese Fighting Fish that has a true double caudal fin with two distinct tails; (two caudal penducles) and not just a split in a single tail.
The dorsal fin mirrors the anal fin in approximate size and shape and has additional rays.
Even double tail splits show an enhanced dorsal fin.
Heart Tails have a partially fused twin caudal fin that gives them their characteristic heart shape.
Fuse Tails have caudalm, dorsal land anal fins fused into one entire fin. Fuse Tail Bettas are very rare and Triple Tails are even rarer.
