For those who are beginners to the fishkeeping hobby as well as experienced aquarists, the attractiveness of the Kuhli Loach also lies in its interesting personalities and interaction in the aquarium. In this article, we will share with you appealing information about the Kuhli Loach and the proper care one should take in order to keep them healthy. If you’ve been keeping them or intend to keep them, don’t miss this article.
What Do Kuhli Loach Look Like?
Kuhli Loach (Pangio kuhlii/semicincta) resembles the eel shape with the body covered with brown to burgundy color and bright orange stripes in between. They have four pairs of barbels around their mouth, tiny beady black eyes, and very small fins behind the middle of their body and their anus.
Good to know: Their barbels are actually very useful. They help sense food and navigate the surrounding environment.
Create An Ideal Habitat for Kuhli Loach
Native to the rivers and streams with low water flow and acidic conditions of Malaysia, Indonesia, and Borneo, Kuhli Loaches normally find their comfort in an aquarium sharing these similarities. To replicate their natural habitat in your aquarium, you may refer to our tips below:
Tank Size
Kuhli Loach should be kept in groups of six or more, and given that they only grow to three to four inches long, a 20-gallon aquarium is enough for them to come out and explore the surroundings.
Filter
Since Kuhli Loaches love hiding, especially in tight spaces, they may occasionally be trapped in the filter of the aquarium. To prevent this from happening, we suggest covering the inlet tube on the filter with mesh or using a sponge filter.
Substrates
Kuhli Loach is shy and sensitive, even when kept together. Thus, you should provide them with lots of hiding places to make them feel secure. Small caves, driftwood, and aquatic plantswork well for that purpose.
Good to know: Another reason why fish keepers fall in love with Kuhli Loach is that they are safe with aquatic plants. Unlike other members of the Loach species, Kuhli Loaches won’t consume algae or aquarium plants. Hence, you don’t need to worry about your planted tank’s aesthetic if keeping them therein.
Aquarium Lid
Kuhli Loaches can jump, particularly when startled, so we encourage you to choose a tank with a cover slide or a tightly fitting lid.
Kuhli Loach Water Parameters
In addition to the tank setup, maintaining proper water parameters is also an important step. We find that Kuhli Loaches will be happy if you allow them to live in an aquarium having the following water parameters.
- Ammonia and Nitrite: 0 ppm
- Nitrate: >30 ppm
- GH: 3-4 dGH (50 - 66.7 ppm)
- KH: 2 - 10 dKH (?- ? ppm)
- pH: 5.5 - 7.0
- Water change: 30% every week
What Do Kuhli Loach Eat?
Kuhli Loaches are scavengers. They love sinkingfish food. During the nighttime, you can see them scooting around and digging the substrate in search of food. Although they can eat the leftovers, you should feed them twice a day (just offer enough food to last for a couple of minutes or so) to make sure they don’t go hungry. Kuhli Loaches are not picky eaters. Flake foods, algae wafers, and bloodworms are acceptable to them.
Good tips: If the other fish in your aquarium eat all the food before your Kuhli Loaches get it, try feeding them at night. We are sure they can get some for themselves.
Best Kuhli Loach Tank Mates
Known for their peaceful disposition, most aquarists keep Kuhli Loaches with other peaceful community fish like Tetras, Rasboras, and even Betta fish. Despite their shyness, Kuhli Loaches often try to interact with their tank mates. It is also worth noting that Kuhli Loachare bottom dwellers. You may often see your Loaches slowly moving at the bottom of the aquarium. Due to this disposition, make sure you don’t keep them together with other dwellers that can be potentially territorial and aggressive.
Just a small reminder that Kuhli Loach prefers living in groups of six or more. Though they are not schooling fish, they are very shy. If you keep it alone, it may feel stressed, insecure, and spend most of its time hiding.
Common Problems When Keeping Kuhli Loach
Kuhli Loach is a nocturnal creature. You should not be upset if you don’t see them splashing around during the daytime. On the contrary, it may show a good sign of their health as it is their ordinary habit. Other activities also considered good signs of health are coming out at night, socializing with other tank mates, and scurrying around all areas searching for their food. The problem occurs when you spot the red flags:
- Not eating
- Showing up mainly during the daytime
- Inactivity at night
- Swellings, ulcers, and reddened areas on the skin
- Rubbing against objects in the tank or on the substrate
Once noticed, you should treat them with proper medication, or in case you don’t know how to handle it, contact the veterinarian for more assistance.
Another common disease your Kuhli Loach may catch is skin issues. This is mainly due to their so-called “scalelessness”. Kuhli Loach is not completely scaleless; however, their scales are really small and very far apart, leaving its skin exposed. This makes them susceptible to skin problems as their protective layer, scales, cannot cover much of their skin. If your Kuhli Loach gets this problem, in addition to treating them with proper medication, you should check their diet and water conditions.

Kuhli Loach Frequently Asked Questions (FAQs)
What is the Kuhli Loach lifespan?
Normally, the lifespan of a Kuhli Loach is around 10 years. This sounds impressive and means that with proper care, your Loaches’ll be around for quite a while!
What is the biggest Kuhli Loach size?
Kuhli Loaches are small, slender freshwater fish that typically grow to 3–4 inches (7.5–10 cm) in length when fully mature. In rare cases, with excellent care and a spacious aquarium, they may reach close to 5 inches, though this is uncommon. Their eel-like body makes them appear longer than they are, and they remain one of the smaller loach species, which makes them well-suited for community tanks of 20 gallons or more. Good water quality, stable temperature (75–82°F), and a diet of varied foods help Kuhli Loaches reach their maximum size.
Do Kuhli Loach eat snails?
Kuhli Loaches are not natural snail predators. Their diet mainly consists of leftover fish food, small invertebrates, worms, and organic debris they find while scavenging along the substrate. While they may occasionally nibble on very tiny snail eggs if discovered, they do not actively hunt or control pest snail populations like Assassin Snails or Loaches such as the Clown Loach. If you are looking to reduce snails in your aquarium, Kuhli Loaches are not an effective solution. Instead, they make excellent, peaceful scavengers that help keep the substrate clean.
