Overview
The Kuhli Loach is a long, skinny, eel-shaped fish from the streams and rice paddies of Southeast Asia, including Malaysia, Indonesia, and Thailand. Its body is banded with dark brown and yellow stripes like a tiger, and it has tiny whiskers called barbels around its mouth that it uses to feel and taste its way along the bottom. Unlike most fish, it looks and moves more like a small snake or eel.
Kuhli Loaches are shy, gentle, and mostly active at night. During the day they love to burrow into soft sand or hide under wood and plants, sometimes poking just their heads out. They feel much braver in a group, so keeping three or more helps them come out and explore. Give them a soft bottom to dig in and lots of hiding spots, and these quirky bottom dwellers will thrive for years.

Built like an eel
The Kuhli Loach has a long, slender body with no big fins, so it wriggles across the bottom and slips into tiny gaps like a little snake.
Night explorers
These loaches are most active after dark. During the day they often hide, then come out at night to hunt for tiny bits of food along the bottom.
Feelers on the face
The whisker-like barbels around the mouth help the Kuhli Loach feel and taste its way around, which is handy for a fish that likes dim, hidden places.
Soft sand and hiding spots
Kuhli Loaches love to burrow, so a soft sandy bottom protects their bodies. Caves, wood, and plants give them the cozy hideouts they crave.

Frequently asked questions
Why does my Kuhli Loach hide all day?
They are shy and nocturnal, so they rest and hide during the day and come out to explore at night. This is normal.
Should I keep more than one?
Yes. Kuhli Loaches feel safer in a group, so keeping three or more makes them braver and more fun to watch.
What kind of bottom do they need?
Soft sand or smooth fine gravel is best, since they like to burrow and could scratch themselves on sharp stones.
What do they eat?
They are omnivores that scavenge the bottom. Feed sinking pellets, wafers, and treats like frozen bloodworms.
