The Swordtail (Xipophorus helleri), is sometimes called the Green Swordtail and is found in rivers, ponds and canals with dense vegetation.
This fish will grow to a maximum length of 10cm and comes in green, black, red, yellow and orange. The male has the swordtail whilst females have fuller bodies. The Swordtail is a livebearer and is easily bred in the home aquarium. It will happily eat flake, frozen and live foods. When keeping the swordtail, females should outnumber males.
The swordtail gets its name because of themales tail extension, whilst the female has a fuller body and looks like a platy. This species is easy to look after and will give birth to live young. The male can be aggressive and need a sufficient number of females around them. A larger tank will help to prevent excess aggression.
They prefer a water temperature between 24-28 degrees centigrade and a PH of between 7.5-8. They will benefit from neutral to hard and alkaline water and are a good community fish.
