Guppy
Poecilia reticulata
Guppies are colorful, hardy livebearers that are perfect for beginners. Males sport spectacular tail patterns in every color imaginable, while females are larger and less colorful. They breed prolifically — a single female can produce 20–50 fry every month — so plan accordingly or keep only males.

Gymnocorymbus ternetzi
Black skirt tetras (also sold as black widow tetras) are hardy, easy-to-care-for schooling fish with a distinctive flowing black anal fin that gives them their name. They come in natural silver-and-black and various dyed/modified versions (GloFish). The natural form is the healthiest choice. They can be mild fin nippers in small groups but are generally well-behaved community fish.
