They mix well with guppies, mollies, platies, Corydoras, rainbowfish, larger tetras, rasboras, and other non-aggressive tropical fish. Avoid housing them with aggressive or fin-nipping species that may target the males' long sword tails. Important Notes Marigold Swordtails are livebearers and breed readily in freshwater aquariums. If both males and females are kept together, fry can be expected regularly. Providing dense planting or floating plants gives young fish valuable shelter. Males may occasionally display mild territorial behaviour towards one another, so maintaining a good female-to-male ratio and adequate space helps minimise aggression. The Marigold Swordtail is a fantastic choice for UK aquarists looking for a hardy, colourful, and active tropical fish that combines brilliant golden-orange colouration with graceful finnage, making it a standout addition to any freshwater community aquarium.
