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.

Hyphessobrycon eques
Serpae tetras are vibrant blood-red schooling fish with a distinctive black comma-shaped marking behind the gill plate. While beautiful, they have a reputation as fin nippers — especially in small groups. Keeping them in schools of 8+ in a spacious tank significantly reduces this behavior. They add bold color to community tanks when kept properly.
