Appropriate Home: In an aquarium with at least 15-gallons of water, an External Power Filter with a BIO-Wheel, 1/4-inch or less of gravel, and an Aquarium Heater adjusted to between 78 and 82 degrees F. Click here for more about warm water aquariums. Like most livebearers Swordtails will do better with 1 Tablespoon of Aquarium Salt per 5 gallons of water. Click here for more about Aquarium Salt. 

Recommended Diet: Floating flake food plus freeze dried blood worms, which are actually mosquito larvae. Both of these foods are sold in most stores that sell pet fish. Click here for more about feeding fish. I feed all livebearers a few Black Worms every other day. Click here for more about Black Worms.

Compatibility: Like all livebearers Swordtails live best in a group with a few male Swordtails and several females. Swordtails are good tank mates for Mollies, Platies, Angels, Corydoras Catfish, Plecostomus, and Bigger Tetras such as Black Skirts, Red Serpaes, and Silver Tips.
