Origin and Habitat

Kuhli Loaches originate from the freshwater streams and slow-moving rivers of Southeast Asia, where they inhabit sandy or muddy substrates. They are commonly found in areas with submerged plant roots, fallen leaves, and driftwood, where they seek refuge and hunt for small invertebrates.

Nocturnal Behavior

Kuhli Loaches are primarily nocturnal, which means they are most active during the night and tend to be reclusive during the day. In the aquarium, they can be observed gliding along the substrate or seeking hiding spots, making them a unique addition to the aquarium’s ecosystem.

Diet and Feeding

In their natural habitat, Kuhli Loaches are omnivorous, feeding on small invertebrates, insect larvae, and detritus. In captivity, they accept high-quality flake food, sinking pellets, and frozen or live foods such as bloodworms, brine shrimp, and daphnia. Providing a varied diet is crucial to their health and vitality.
