Kuhli Loach (Pangio kuhlii)

Kuhli Loaches are a peaceful fish and relatively hardy, and can adapt to a variety of water parameters, and prefer to be kept in schools of 3 or more.

Because of its beauty and its tank cleaning abilities, they have become quite popular in the aquarium hobby.

The kuhli loach is shaped like an eel with slightly narrowed sides, you will see four pairs of barbels around its mouth, and tiny fins.

The dorsal fin starts behind the centre of the body, and the anal fin behind this.

Their eyes are covered with clear skin, and the body has ten to fifteen dark brown, almost black upright bars, and the space between them is a salmon pink to yellow with a light underside.

Even though this species is small in size, they are more suited to experienced aquarists because they are susceptible to diseases, they have a head with no scales, and they are sensitive to medications.

In the home aquarium, the Kuhli Loach will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.
