The Swordtail (Xiphophorus helleri) comes in many different colors with the males being easily identified by their signature sword like tail. The Swordtail is an extremely hardy fish that can adapt to a wide range of water conditions.
They are livebearers which means that the baby fish come out free swimming. Like their livebearer counterpart, the guppy, the swordtail is a prolific breeder and a female will give birth about once every 28 days. If you are interested in breeding them, please check out the breeding livebearers page for more information.
Some hobbyists have reported problems with aggression among male swordtails when keeping multiples. It may be a good idea to limit the number of male swordtails in your tank. A good mix may be three females to one male.
They will eat most fish foods including flakes, frozen, freeze dried and live foods such as brine shrimp.
