"Blue Male Crowntail Betta (1.75""-2.25"" Length)"

"Blue Male Crowntail Betta Also known as Siamese Fighting Fish, Combattant (Canada), Trey kroem phloek (Cambodia), or Cá lia thia (Vietnam). This specific fish comes in shades of blue. There may be hints of reds or greens. 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. Blue Male Crowntail Bettas have stunning tails with single or double ray patterns in a range of colors. The blues in Bettas can range from Steel Blue to Royal Blue. This finnage was first acknowledged as an official Betta Tail and Fin form in 1997 in Indonesia. Bettas will ""flare"" their fins when disturbed or threatened. The male Betta will attack another Betta (Male or Female) 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."
