Live or artificial plants provide cover, help reduce stress, and give fry hiding places if breeding occurs. For best results, keep swordtails in groups with more females than males. A good ratio is one male with two to three females to help reduce stress on females and encourage natural behavior.

Suitable tank mates may include platies, mollies, guppies, peaceful tetras, rasboras, danios, corydoras, and other peaceful catfish. FAQ Are Tiger Swordtails good for beginners?Yes.
