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.

Hillstream loaches are fascinating flat-bodied fish that resemble tiny stingrays. They are specialized for life in fast-flowing, oxygen-rich streams and use their modified pelvic and pectoral fins to grip smooth rocks in strong current. Their unique appearance, algae-eating habits, and cool-water preference make them popular with experienced fishkeepers looking for something different.
