Great first fish! Livebearers are unlike other fish in that they do not lay eggs; the young develop inside the mother and when born are significantly larger than the offspring of similarly sized egglayers. Species such as the guppy, platy and swordtail are incredibly prolific and are some of the best known, and most colouful aquarium species
