Female Betta Super Delta

What is a delta tail betta fish?

The delta tail is an unusual variety of the betta, or Siamese Fighting fish, which belongs to the Gourami family of fishes.

Delta tails are named after the Greek letter. The fish’s tail becomes narrower as it gets closer to the body, widening toward the edges. So it resembles the triangular shape of the Greek letter, Delta (∆)

Another variation of the delta tail is called the super delta tail betta. That variety of betta fish has a tail that flares to almost 1800. The spread of a regular delta betta’s tail is much smaller than that. The edges of the tail are uniform with no combing or crowing.

Delta tail bettas originate from parts of southeast Asia, including Vietnam, Indonesia, Thailand, and Malaysia. In these regions, where the fish live in the shallow waters of rice paddies, ponds, and waterways. Bettas grow to a maximum of three inches in length and have a lifespan of two to three years, which is typical for most small tropical fish.
