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.

Their dark blue body is covered in iridescent pearl-white spots, with bright orange-red fins striped with black. Despite their exotic appearance, they are hardy and easy to care for — one of the hobby's best-kept secrets for nano tanks.
