Types of LivebearersThere are quite a number of livebearer species available, but the most popular choices for the aquarium fall into the following groups:
- Guppies -The most popular of all aquarium fish, these tiny fish are highly sociable and beautiful to look at, with each individual having different colours, the males especially vivid. They can be happy in both freshwater and marine tanks.
- Mollies -Including the popular black molly and exotic sailfin molly, these fish can grow fairly big and are highly active. They are very hardy and some species are comfortable in marine aquariums.
- Platies -Fast, active and highly sociable, these charming little fish do best on a diet which contains plenty of live food.
- Swordtails -These brightly coloured, energetic fish like to jump, so make sure your tank has a secure hood. They prefer slightly salty water. They should not be kept with goldfish.
