Species Profiles
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.

Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.
