Black Kuhli Loach
To protect our animals and to ensure they get to our customers healthy, we will only ship orders with Nano Fish via UPS Next Day Air.
The Black Kuhli Loach is a great peaceful freshwater fish. They are natural scavengers and will constantly scurry around the bottom of the tank looking for food. They have a relatively long lifespan for a freshwater fish, living up to 10 years if properly cared for. They can grow up to 3-4 inches in captivity. Some hobbyist observe that they might be more interactive than the regular Kuhli Loach.
Black Kuhli Loaches are pretty easy to care as long as they are introduced to a mature, cycled tank. They can acclimate to a wide range of parameters. The following are our water parameters we keep them at:
| Parameter | Value |
|---|---|
| Temperature | 72-78°F |
| PH | 6.0-7.0 |
| Water Hardness | 2-8 dGH |

My Black Kuhli Loach has been in the tank for three months and is very active. It spends most of its time near the bottom, picking up small food particles. The fish is calm and doesn’t stress other tank mates. Easy to maintain and very peaceful.

I noticed it’s more curious than other Kuhli Loaches. It seems to follow the movement of the filter and occasionally swims to the surface. The water parameters are stable, and the fish has adapted well to the tank.

Great addition to my community tank. It doesn’t compete for food and helps clean the substrate. I’ve kept it for over six months and it’s still healthy and active.
