Above: This picture shows a very nice premium quality mature male Black Swordtail. There are of course also females, which do not have a sword.
This Black Sword has some interesting colors. Although he may not seem completely black, he has a great blue hue that shines on his black scales, making for a great schooling Sword.
Comments: This is a Premium Pet Fish, and we never see Premium Swordtails like these in any of the live fish stores or in the online fish stores that we visit.
Premium Pet Fish are more energetic, hardier, and have brighter colors with a beautiful metallic sheen.

Origin: Swordtails are one of the most colorful and most popular aquarium fish.
Their ancestors originally lived in southern Mexico and the east coast of Central America, but Swordtails are now found living in aquariums throughout most of the world.
There are many color varieties for sale in our store.
Maximum Size: In aquariums, Swordtails can grow to be about 5" long, including their tails.
Behaviors: Most Swordtails are very active swimmers, and chase each other, but are rarely too aggressive.
Female Swordtails release live baby fish about once a month when kept in good water and fed lots of premium food.
Compatibility: Some recommended tank mates include Corydoras Catfish, Danios, Barbs, Rainbowfish, Plecostomus Catfish, Mollies, Gouramis, and other medium sized fish.
