Assorted Lyretail Swordtail

(Xiphophorus hellerii)

The Swordtail comes in many different colors with the males being easily identified by their signature sword like tail. This 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, this 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 males when keeping multiples. It may be a good idea to limit the number of males 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.

This variant has the lyretail gene, which gives males swords on both the top and bottom of the caudal fin.
