Water Parameters and Tank Size

Kuhli Loaches thrive in their natural habitat so it is important to create or at least try to imitate the same environment. Kuhli fish prefer warmer temperatures around 73 to 86 degrees Fahrenheit. Their water should be soft, acidic, and low-to-medium hard with a pH between 5.5 to 6.5. The water hardness should not be more than 5.0 dGH. 

If you are considering petting a sole kuhli fish then the tank size of around 15 gallons would be enough. However, in the case of more than one kuhli fish, you must add 4 to 5 gallons per kuhli fish. 

Tank Decore and Precautions

Struggling with aquarium equipment is a common issue and when it comes to Kuhli fish it can become fatal. As Kuhli Loaches are bottom dwellers and constantly finding new places to hide, the aquarium equipment can be dangerous if not taken care of. 

One of the common problems is with the aquarium filters and inlet tube on it, as you must cover it with fine mesh or it can be a fatal trap for your kuhli fish. Another thing that you should consider is to cover the fish tank if not already, as kuhli fish are known to jump out of the tanks.

Kuhli loach’s tank should be filled with sand or fine-grained gravel substrate that can’t scratch their sensitive bellies. Kuhli fish likes environments with hiding places under rocks or other objects, so many hiding places must be available for them; live or plastic plants and artificial caves are ideal.

They also need plenty of oxygen because if their habitat doesn’t have enough oxygen, they will suffocate. Kuhli fish are relatively hardy in captivity, but they can be susceptible to diseases if the water quality is not maintained correctly or their environment becomes overcrowded.

To prevent this issue, it’s important that Kuhli loach tanks have plenty of aeration from a power filter with a strong enough pump to circulate the water.
