Guppies, platies, mollies, swordtails and Endler's give birth to live young. They're hardy, colourful and active, and they breed readily, so plan for the babies.
Water
Most livebearers prefer harder, slightly alkaline water (pH 7 to 8). Keep the tank cycled and change part of the water weekly.
Babies
Females can give birth every month or so and store sperm for several broods. Keep more females than males so no female is harassed, and give fry plants to hide in, or keep only one sex if you don't want young.
Food
Feed a quality flake or micro-pellet with some vegetable matter, and occasional frozen or live foods.
