Swordtail Tank Mates

Swordtails are peaceful and social fish that do well in community tanks, making them compatible with a variety of tank mates. When selecting companions for swordtails, it’s important to choose species that share similar water parameters and temperaments. Ideal tank mates include other livebearers such as platies, mollies, and guppies, which thrive in similar conditions and display complementary behaviors. These species are also active swimmers, which helps create a lively and dynamic aquarium environment.

In addition to livebearers, swordtails can coexist with other peaceful fish like tetras, rasboras, and danios. These species are small and non-aggressive, making them a good fit for a community tank. Bottom-dwellers like corydoras catfish and bristlenose plecos are also excellent choices, as they help keep the tank clean by scavenging leftover food and algae. However, it’s important to avoid housing swordtails with aggressive or larger fish that might bully or outcompete them for food, such as cichlids or large barbs.

When keeping swordtails in a mixed-gender group, it’s wise to maintain a ratio of one male to two or three females to prevent excessive harassment of females by males. Additionally, providing plenty of plants and hiding spots in the tank can help reduce stress and give fish areas to retreat if needed. By carefully selecting compatible tank mates and creating a well-structured environment, you can ensure a harmonious and thriving community tank that includes swordtails.
