Kuhli loaches are scavengers, and they will eat anything that reaches the bottom of the tank. They prefer to feed at night, but you can teach them to feed in the day in the home aquarium.

Despite not being fussy, and eating most things you offer them, they do prefer a meat-based diet, so frozen and live foods such as tubifex, brine shrimp, daphnia, or blood worm is the way to go.

To give them a well-balanced diet, you can also feed them vegetables, granules, fish flakes and sinking pellets.

Sexing the Kuhli Loach

It isn't easy to differentiate males from females, and the only noticeable difference is, in the males, the pectoral fins are more abundant and are more paddle-shaped. The females are slightly larger, especially when carrying eggs.

Breeding the Kuhli Loach

Breeding in the home aquarium can be challenging, although there have been some success stories.

The best way to breed this species is to have a separate tank with plenty of hiding spaces, a bunch of Kuhli loaches, dim lighting and steady water quality, as well as feeding them plenty of food to encourage spawning.

Kuhli Loaches will reach sexual maturity around two years old; when spawning is happening, you will notice the male preying upon the female.

Once he has her attention, he will place his head next to hers and holds her with his pectoral fin in a warm embrace.

The pair will then move very quickly around the bottom of the tank and then swim towards the surface where the female will spawn, and her small light green eggs will stick to the plants or fall to the bottom of the tank.

A female can produce hundreds of eggs.

Once spawning has taken place, and the eggs have been laid, you will need to remove the parents, to avoid them consuming the eggs. The eggs will start to hatch about a day later, and small green fry appears, then four days after that, they will become free-swimming.
