Black Kuhlii Loach

The Black Kuhli Loach, also known as Pangio semicinctusby its scientific name, is a fantastic freshwater fish for those looking for a peaceful addition to their aquarium. These little buddies are natural scavengers, eating up all sorts of things to keep your aquarium clean, and with an average lifespan of 10 years, you'll be enjoying their company for a very long time.

For whom is the Black Kuhli Loach suited?

These small fish may seem like an attractive addition to any aquarium due to their size and natural tendency to clean up the waste floating around in your aquarium without creating much themselves, but taking care of them is more complicated than you might expect. These fish have no scales and are somewhat prone to disease, so we recommend that you have some experience in caring for scale-less fish if you're planning on getting them.

What are they like?

The Black Kuhli Loach is a real night owl. They are active mainly at night and can peacefully co-exist with most other fish. During the night, they will look for food that sunk to the bottom of the aquarium. On top of that, their natural curiosity will drive them to explore any crevices and caves that might be around in their habitat.

The ideal conditions for the Black Kuhli Loach

Despite the fact that these fish are scavengers, they still require a relatively clean, well-oxygenated tank. They highly prefer a soft substrate, as it makes searching for food more manageable, so sand or fine gravel would be best. The water should be soft, slightly acidic, and at a temperature of 73 – 86 °F, as these are tropical fish. Further, you should make sure that there is moderate lighting in their habitat.

    So lively

    These guys are so much more active in the daytime than the striped ones I have. Healthy, young, and so lively! Very happy.

    ‘Kuhl’ Fish

    My order of Kuhli Loaches arrived alive and healthy, and have acclimated well to life in my aquarium. They only make the rare appearance during the day and are quite skittish, but when they do come out of hiding they are a real treat to watch. The substrate in my tank is pea river gravel and I have been amazed at how easily and quickly they can burrow through it. I have observed one burrowing down on one side of a clump of micro sword and popping up on the opposite side nearly as soon as it disappeared from view. That said, they do sometimes uproot plants, so bear that in mind if it is a concern to you. These fish will eat practically anything you feed the other inhabitants of the tank, including algae wafers, and seem to have very big appetites. They do appear to have a high growth rate, which may contribute to their healthy appetite, so idk if that is true of mature specimens. Overall I am very pleased with these fish and the job they do cleaning up whatever food makes it to the substrate.
