Dwarf Chain Loach

The Dwarf Chain Loach is the smallest loach species available in the aquarium hobby, reaching only 2-2.5 inches. Native to Thailand, these tiny loaches have a distinctive chain-like pattern along their sides and are perfect for small community tanks. They are active, social fish that should be kept in groups of 6+ and are excellent for controlling pest snails in smaller tanks. Unlike larger loaches, they can be kept with shrimp and are peaceful community residents.
