Species Profiles
Betta Fish
Betta splendens
The Betta fish (Siamese fighting fish) is one of the most popular freshwater aquarium fish in the world, known for its stunning flowing fins and vibrant colors. Males are territorial and should be kept alone or with carefully chosen tank mates. Despite their reputation as low-maintenance fish, bettas thrive best in heated, filtered tanks of at least 5 gallons.

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.
