Black Coolie Loach | Pangio semicinctus

The Black Kuhlii loach (Pangio semicinctus), also called the Black Coolie Loach, is a peaceful, bottom‑dwelling fish that helps keep your tank clean. These loaches are great scavengers, they eat leftover food and waste so you don’t have to worryas much about overfeeding or ammonia spikes. They’re easy to care for, which makes them a good choice for beginners. Because they have no scales, it’s important to keep their water parameters stable and use soft sand (or other smooth substrates) on the tank bottom to avoid scratches that could lead to infections.

Black Kuhlii loaches are shy during the day and like to hide under plants or in caves. When the lights go off at night, they come out to wander and feed. Their scaleless skin means they can get sick more easily if water conditions change too much, so regular water changes and testing is a good practice. These loaches are very peaceful and get along well with other non-aggressive fish, making them a perfect addition to any community aquarium.

    Kuhliis are doing great. Kuhliis of any kind are my favorite. Never a dull moment with them. Thanks for everything.

    Best fish, no argument

    Very cool fish, very interesting fish, though four of them arrived dead. I Wouldn't say it was the company's fault more like my fault, no, definitely my fault. I Didn't know it came with instructions, I left my brother to handle it and give him my instructions of floating the bag, while I left for work. The one's that are still alive are pretty cool though, very good fish, would buy more.

    Great customer service

    After placing my order, I was able to change and even add to that change. Very happy with fish. I ordered again this week and I’m excited to see my new fish.
