Species Profiles
Kuhli Loach
Pangio kuhlii
Kuhli loaches are eel-shaped, nocturnal bottom dwellers with striking black and orange/yellow banding. They are shy, peaceful, and love to burrow in sand and hide in tight spaces during the day. Despite their snake-like appearance, they are completely harmless community fish that become much more active and visible when kept in groups.

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.
