AQUARIUM CARE: One of the most popular aquarium fishes, and a great candidate for the beginners aquarium. The wild type swordtail, or green swordtail is very common, but it also comes in many other colour forms and shapes: typically with varying degrees of red, white, yellow and black.

This is a very tough species that can adapt to most water conditions, though preferring slightly harder water. Sexing is easy as the males have a 'sword' on their caudal fin; females are slightly larger and overall more rounded.

This is a great community species, although males can get somewhat aggressive at times, so provide ample hiding places for subdominant males females and fry.

BREEDING: A very easy livebearer that gives birth to large fry. Females can be seperated (breeding trap) when heavily pregnant to avoid unwanted male attention, and to avoid predation of the newly born fry. Even when bred in a well-stocked community tank, some fry will survive. Swordtails will interbreed with platies (Xiphophorus maculatus) if kept in the same aquarium.

Fishkeeping Facts and Tips

Too many fish? Overstocked tanks stress the fish in many ways: competition for food and space, bullying from other fish, deterioration of water quality and increased concentration of disease vectors. A lightly stocked tank will always be easier to care for, with more stable water quality
