Guppy

scientifically known as poecilia reticulata, the guppy comes in two major forms: fancy guppies and feeder guppies. If you are a beginner and you want a good quality guppy, you should get a feeder guppy because fancy guppies have been inbred and are poor quality. Wild guppies are also a good pick because they are less inbred.

behavior
Guppies have the annoying habit of eating their fry after their short time of parental care is over. Otherwise the guppy is a nice social addition to your aquarium.

Be careful adding guppies to aquariums with barbs, because they could/will nip at their fins.

Guppies are livebearers, which mean that they incubate their eggs inside their body. Because of this guppies have lots of offspring.

feeding
Guppies will eat small live foods, flake foods and prepared foods.
