Species Profiles
Goldfish
Carassius auratus
Goldfish are among the longest-kept ornamental fish, with a history spanning over 1,000 years. Despite their reputation as easy, bowl-dwelling pets, goldfish actually require spacious tanks with strong filtration. They are cold-water fish that should not be kept with tropical species. Common varieties include comets, fantails, orandas, and ryukins.

Sewellia lineolata
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.
