With their peaceful nature and unique, eel-like appearance, Kuhli Loaches are a fantastic addition to any freshwater aquarium. Thinking of incorporating some Kuhli Loaches into your tank? Here at Pond Planet, we’ve created a Kuhli Loach care guide that will tell you all you need to know about looking after these wonderful creatures.
About Kuhli Loaches
Also known as Coolie Loach, Leopard Loach or Cinnamon Loach, Kuhli Loaches originate from Indonesia and the Malay Peninsula and are part of the Cobitidae family. While they are quite shy by nature, they are sociable fish and prefer some companionship. While Kuhli Loaches are not schooling fish, they do form into groups and make peaceful tank mates for other small, unaggressive fish species.
As Kuhli Loaches are nocturnal, they will be relatively quiet during the day and much more active by night.
While Kuhli Loaches make fantastic pets, due to the fact they have very fine body scales and no head scales, they are more prone to some diseases and are also sensitive to medications. For this reason, they are generally considered more suitable for more experienced fish keepers.
How big do Kuhli Loaches grow?
While in the wild Kuhli Loach can grow to a maximum of five inches, they are usually around three inches in aquariums.
The Kuhli Loach lifespan
Well looked after, your Kuhli Loach can live up to 10 years!
The Kuhli Loach Diet
What do Kuhli Loaches eat?
When it comes to the Kuhli Loach diet, these fish will eat most things. Peaceful scavengers, Kuhli Loaches are bottom-dwelling fish, which means they’ll source their food at the bottom of the tank by typically sieving mouthfuls of substrate. Kuhli Loaches are omnivorous fish, which means, in nature, they consume small crustaceans, larvae, and plants found on the river bed.
You’ll need to feed Kuhli Loach several times a day. They can be fed flakes and pellets that will sink down to the bottom of the tank where they like to dwell. However, it’s important that a Kuhli Loach diet contains a lot of variety and be largely meat-based, including live food such as bloodworms and brine shrimp.
Do Kuhli loaches eat algae?
Kuhli Loaches are known for being good cleaner fish. As they scavenge for food, they will eat some algae at the bottom of your tank that grows on the gravel. By burrowing and scavenging, they can help to loosen food and dirt in the substrate that can subsequently be cleaned by your aquarium filter.
Kuhli Loach Tank Requirements
Kuhli Loach water temperature & requirements
As Kuhli Loaches are tropical fish, their tank water should be kept between 24 – 30°C (75 – 86°F). Their water should also be soft (0-5 dGH) and slightly acidic (pH 5.5-6.5) and they require moderate lighting conditions. It’s highly important to keep their water well-oxygenated and clean using a filter.
Note: Your filter will need a cover on top of the outlet and inline pipe to prevent your Kuhli Loaches swimming in and getting trapped.
Kuhli Loach tank size
Though Kuhli Loaches are small, the minimum tank size you’ll need is approximately 20 gallons. Remember, as they are bottom-dwellers, it is best to have a long, rectangular tank that gives them plenty of space rather than a high tank.
Substrates and tank decor
Kuhli Loaches like to burrow and they use their barbels to sift through the substrate to find their food. Therefore it’s very important to provide them with a soft substrate, preferably sand or a fine gravel mix.
As Kuhli Loaches are quite shy and curious fish, they need a lot of space to hide and explore. You’ll need to include lots of vegetation, as well as decor including large rocks and shrimp caves to provide them with shady places they can retreat to. If your aquarium is too sparse it will cause your Kuhli Loaches stress.
With their peaceful, undemanding nature and interesting appearance, Kuhli Loaches can make wonderful additions to a home aquarium, providing you have the experience required to create the right habitat for them and prevent the onset of disease.
