Important Notes

Swordtails are livebearers and breed readily in aquariums. Males may show dominance behaviour, so keeping more females than males helps reduce aggression. They prefer slightly harder, alkaline water conditions.

The Mixed Swordtail is a great choice for UK aquarists looking for a colourful, active, and easy-to-keep fish that adds movement and variety to community aquariums.
