Swordtails thrive best in groups of 4 to 6 fish, with a higher number of females than males. It is recommended to keep at least two or three females for every male to reduce aggression and stress among them.
Swordtail fish are generally peaceful and friendly, but males can sometimes show aggression towards each other. This behaviour is usually manageable by maintaining a higher ratio of females to males in the tank.
Yes, swordtails are suitable for community tanks as they get along well with other peaceful fish of similar size, such as platies, mollies, and cory catfish. However, they should not be housed with aggressive or fin-nipping species since swordtails cannot defend themselves easily.
Swordtails are relatively easy to care for due to their hardy and adaptable nature. They require a well-maintained aquarium with proper filtration, lighting, and temperature control, as well as a tank size of at least 80 litres for a small group, with plants and open swimming areas.
