(more) Brian Huebner The wiggly little Kuhli Loach keeps quite busy scurrying around plants and roots, squeezing between rocks, and exploring cracks and crevices searching for food. These great little cleaners make a welcome addition to a community aquarium, snacking on foods left uneaten by the other fish!Kuhli Loach Contents These active fascinating little fish are exported by the millions. Though peaceful, the Kuhli Loach is nocturnal and is most active at night. They can also be quite shy and will seldom be seen if kept alone. This doesn't mean they are a schooling fish, as they are not, but they are more comfortable and more likely to come out of hiding if they have some companions. A group of a half dozen or so will make them more prone to behave as they would in nature. They are quite hardy and can live for several years. The Kuhli Loach's body has a pinkish yellow background color crossed by 12 to 17 vertical dark bars and has three bars on its head. There are no scales on the head, the eyes are covered by a transparent skin with a short spine in front of them, and they have 3 pairs of whisker-like barbels. The dorsal and pelvic fins are set very far back with the anal fin set at the end of the base of the dorsal fin. This little fish was originally named and is best known as the Kuhli Loach or Prickly Eye, but there are quite a few other common names often associated with this fish. For example, in the United States this loach is sometimes also called the Coolie Loach, Giant Coolie Loach, or Leopard Loach.

| Data provided by FishBase.org |
Care and feeding: Since they are omnivorous, the Kuhli Loach will generally eat all kinds of small live and frozen foods and meat based foods are relished the most. They also like sinking pelleted and tablet foods, flakes, and a bit of vegetable foods such as algae wafers. To keep a good balance give them a high quality prepared food everyday. Feed tubifex worms, brine shrimp (either live or frozen), mosquito larvae, and daphnia as a treat.
This fish will do well in a smaller aquarium (ideally 20 gallons or so) with lots of plants and places for retreat, such as rocks, caves, and roots. Also use subdued lighting. They do best in soft, slightly acidic water with frequent water changes of about 10% a week. The substrate needs to be a fine gravel or sand that does not have sharp edges and they will also enjoy a bit of peat moss spread over the substrate to simulate the natural mulm found in their native environment.
Distribution: The Kuhli Loaches are found in southeast Asia; Sumatra, Singapore, western Malaysia, Java, Borneo, and Thailand. They live in sandy areas of rivers and mountain streams.
Size - Weight: These fish can get up to 4 inches (10 cm), though they are usually smaller in the aquarium.
Social Behaviors: A peaceful community fish and a great scavenger of uneaten foods that settle to the bottom of the aquarium. They hide during the day, but are quite lively and active in the evening. Though they do not school, they will be more likely to come out of hiding if they are kept with some companions. A singly kept Kuhli Loach will seldom be seen.
Sexual Differences: Unknown, though a female with eggs will be plumper. (See the top photo above.)
Water Region: Top, Middle, Bottom: These fish are mostly bottom dwellers.
Acceptable Water Conditions: Hardness: to 5 ° dH
Ph: 5.5 - 6.5
Temp: 73-86 ° F (24-30 ° C), they can tolerate low 80 °s for a short period.
Breeding/Reproduction: Not much is known about the breeding habits of the Kuhli Loach, though they have been bred successfully in the aquarium. They scatter bright green adhesive eggs underneath floating plants where the eggs then attach to the stems and roots. The eggs have been described by Herbert Axelrod as a type of bubble nest, with each egg enclosed in a bubble. They are not yet bred commercially.
Availability: The Kuhli Loach is readily available.

I have a 55 gallon community tank with mostly Tetras, White Clouds, one Male Betta, two Alge Eaters, two Plecos and three Black Kuhli Loaches. The bottom is heavily vegitated and has many rock formations for them to hide. I rarely see the Loaches except when moving from one hidding spot to another, until yesterday when I noticed I had babies. I'm not sure how many (5+), but now they seem to be everywhere.

I have one kuhli and it is pitch black and looks so cool. At first when I got it, it hid all the time and I thought it was going to die cause I never saw it eat. But now it's out all the time and I see it cleaning the bottom.

I love my Kuhlis!! I got five of them 'cause I read they were more active in groups and I absolutely love them. They're so much fun to watch, almost as if they have a human personality, awesome loaches..... and they aren't even afraid of my Kribensis cichlids!

| Some of the bestest comments - here's the beef! | ||
I have had a kuhli loach in a heavily planted 20 gal. tank for 12 years. A couple of years ago, when I had not seen him for several weeks, I thought he must have died. Then I noticed my shrimp disappearing. He eventually ate all my shrimp and looked like a loach on steroids! I now make sure he is well fed. I don't know their lifespan, but he is going on 12 and 1/2 years. He has survived everything else several times over.

These snake like fish make a pretty good clean up crew. I have 5 of these little snake like fish and they eat most of my tanks left overs. The corries help as well. These fast little critters make an excellent addition to a non aggressive topical tank. I've had no trouble with them except I don't know what little mischief they get up to. I'm not even sure if they are all alive. I have 2 big ones who are always out and about. If you do find an interest in these fish and you want to buy, make sure they are in a small shoal of 4 or more. If you have 2 or 3 you wont see them often. If you only have one, don't expect to see him often. When they are visible they usually travel in 2's or 3's.

I bought three Khuli loaches about a week ago, they were all very active and healthy looking. Though one of them had a white spot on him like he had rubbed the skin off. The first few days they were fine but today they were flopping about like they were out of water! I checked their water and everything was as it should be, so I have no clue what is going on. The water is soft and somewhat acidic, Nitrate 0,ph 7.5. and all of the other fish act fine...I need help.

I have 2 of these loaches is that enough? I haven't seen him eat, I know they're nocturnal but should I do anything?
