Male Deltatail Betta

Also known as Siamese Fighting Fish, Combattant (Canada), Trey kroem phloek (Cambodia), or Cá lia thia (Vietnam).

The Male Betta is well known for its jewel-bright colors and spectacular finnage. Bettas are anabantids (Derived from the Greek Verb anabaino, meaning "to go up") which physiologically means they have two methods of breathing. Bettas breathe from their labyrinth organ which enables the fish to breathe from the surface. Bettas also breathe through their gills like other fish.

Male Deltatail Bettas have a distinctly triangular-shaped tail with crisp edges and sharp angles. The tail of a Delta is symmetrical, and although the angle is generally wide they are generally 130° or less in tail span. Anything more than 130° but less than 170° is considered a Super Delta Tail Betta. Bettas will "flare" their fins when disturbed or threatened.

The male Betta will attack another Betta and have been known to attack similar-looking fish. It is recommended that only one male Betta is housed in an aquarium with plants and very little current.
