Kuhli Loach Facts

Kuhli Loaches, sometimes referred to as Coolie Loach or Leopard Loach, are known for their unique eel-like body shape. They are also known as “cleaning fish”, as they love to dwell at the bottom of the tank to look for leftover food. Kuhli Loaches are also considered peaceful fish that require an intermediate level of caretaking.

However, despite their peaceful nature, I would recommend only more experienced aquarists to keep them in their tank. The main reason for this is that they are prone to diseases. Moreover, they are sensitive to medications and are easily affected by changes in water parameters.

Kuhli Loaches are especially popular amongst experienced aquarists because of their size. They only grow up to 3 to 5 inches in length and have a small bioload. Therefore, because of these reasons, aquarists like to keep these peaceful and small Kuhlis to use them as cleaners for their tanks.

Although Kuhli Loaches are not schooling fish, they are more comfortable when kept with other suitable tankmates. This is mainly because they are very shy fish and will prefer to hide in their little spots within the tank if kept alone. Thus, for more information about which fish species get along the best with Kuhli Loaches, read the following section!

Most Suitable Tankmates For Kuhli Loach

Since Kuhli Loaches are small and peaceful fish, I would recommend you to keep them with other small non-aggressive fish. Some examples of the most suitable tankmates for Kuhlis would be as follows.

However, make sure not to place them in a tank with large territorial fish like Arowanas, Cichlids, and Red-Tailed Sharks.

How Many Kuhli Loaches Can You Put in a 10-Gallon Tank?

As Kuhli Loaches grow up to 3 to 5 inches in length, the ideal number of Kuhli Loaches in a 10-gallon tank is around 4. However, you can put up to 6 Kuhlis in a 10-gallon tank too. In the end, the ideal number of Kuhli Loaches depends on how many other fish you already have in your tank. For this, you can read the section below that discusses how much space a single Kuhli Loach requires.

Now you may be wondering why you cannot simply buy one Kuhli Loach for your tank. This will not work out too well for your Kuhli or you because, when left alone, Kuhlis tend to hide in little crevices of the tank since they are very shy by nature.

Moreover, they prefer to hide out during the day and come out to look for food at nighttime. Hence, if you put only one Kuhli Loach in your tank, then chances are you will barely ever see it swimming out in the open!

How Much Space is Ideal for Kuhli Loaches?

The golden rule when it comes to fish is one gallon of water per one inch of fish. However, big-bodied fish like goldfish and cichlids usually require two gallons of water per one inch of fish.

You can learn more about cichlids from our articles:

Nonetheless, since Kuhli Loaches only grow up to 3 to 5 inches in length, they are considered fairly small fish. Thus, each Kuhli Loach requires around 3 to 5 gallons of water.

Kuhli Loaches are also active fish so they need a decent amount of space to swim around too.

So, if you do not have a lot of other fish in your 10-gallon fish tank, then you can add around 4 Kuhli Loaches to maintain a healthy environment for them. You can add up to 6 Kuhli Loaches in your 10-gallon tank if they are the ONLY fish in the tank!

How to Maintain Your 10-Gallon Tank for Your Kuhli Loaches?

Kuhli Loaches are freshwater fish that require a bit of attention as they are susceptible to diseases such as Ich or those caused by parasites. Hence, when introducing them to a new fish tank, you will need to monitor them carefully to ensure that they are adjusting well to the new environment.

Now that you know a bit more about their temperament and how many Kuhlis you can keep in your 10-gallon tank, I will tell you about some basic maintenance measures that you should take.

Filter Maintenance

Since Kuhli Loaches require oxygenation, I would suggest an under gravel filter to improve oxygenation. You should also place fine sand in your tank because Kuhli Loaches love to burrow themselves in it to find food. And since they have very fine body scales and no head scales, it could prove harmful to them if you place courser sand in your tank.

Moreover, it may be best to cover the inlet tube of your aquarium filter with a fine mesh. If this is not done, the chances are high that your Kuhli wriggles its way into the filter and gets trapped in it!

Finally, make sure to clean your filter at least once every 4 weeks. However, do wait at least a week from your last cleaning, as your Kuhlis and other fish will require some time to adjust to the new tank conditions.

Ideal Tank Decor for Your Kuhli Loaches

In their natural habitat, Kuhli Loaches live around thick vegetation. Hence, to recreate this in your fish tank, you can spread peat moss inside the fish tank. Espoma Peat Moss is a natural and organic sphagnum peat moss for improving heavy soils (8 qt, Pack of 1).

You can also add a few large rocks and big pieces of driftwood, as these will provide your Kuhli Loaches with places to hide.

Moreover, it is also a good idea to cover your tank with a lid, as Kuhli Loaches tend to jump out of the tank. This is especially necessary if the water level in your fish tank is very high!

Ideal Water Parameters for your Kuhli Loaches

Finally, the ideal water parameters for your Kuhli Loach are as follows.

  • The water should be soft, 0 dGH to 5 dGH. Maintain Aquarium Water Hardness from our Freshwater Aquarium Guide.
  • The water should be slightly acidic with a pH of 5.5 to 6.5.
  • The temperature of the water should be 73 °F to 86 °F
  • Kuhli Loaches require a soft substrate such as sand and fine gravel mix. For sand, you can use Carib Sea ACS05840 Super Naturals Crystal River Sand for an Aquarium of 5-Pound. Similarly, you can use 12 Pounds River Rock Stones, Natural Decorative Polished Mixed Pebbles Gravel, Outdoor Decorative Stones for Plant Aquariums, Landscaping, Vase Fillers.
