Species Profiles
Kuhli Loach
Pangio kuhlii
beginnerpeaceful15+ gal
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.

Oscars are large, intelligent South American cichlids often called 'water dogs' for their interactive personality. They recognize their owners, beg for food, and can be hand-fed. However, they grow fast, produce massive waste, and need at least a 75-gallon tank.
