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.

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.
