I wanted to name our little friend xray because you can see right thru his eye and out the other side. Cool little buddy. bloop bloop bloop... :) hunnys daughter named him col. sanders.? these fish are cool!! We're down to 2 (had 4) that are doing very well. New tank and just learning...it's not quite as simple as we thought it would be. Buy tank, add water, add fish. Learning that there's a little more to it than that. Sorry lenny (fish 1) and wigga (fish 2). And RIP Red. (poor little betta..learning curve..oops. and where can we buy a panda telescope? Anybody know? :) bloop bloop bloop... bettybloop
We have two large iridescent sharks we are looking to find another home for. Our tank is too small and they are very large. Do you have a big tank? Do you know they can grow 3-4 feet? Where are you located? Jackie
Hi! I thought I was buying a danio but it ended up being PetCo sold me a super small juvenile Ranbow Cichlid! Now I would like to buy a similiar one so this lil guy can have company. If you know where I can find another one, please let me know! I haven't been able to find another one at Petco since I bought mine...thanks! Kobie
I am looking for a source of several hundred cichlids. They will be research animals, not pets. I am doing a study looking at male mate choice and fecundity based on selection of female in relation to the size of her orange 'patch'. The animals will not be required all at once (actually it is preferable that they are not all at once) but we will need about 50 at a time. We need fish which are greater than 1 inch in length and about twice the number of females to males.
If anyone has any suggestions! Kristy
Looking for a 6in+ sized cat, if you have one let us know Erich
The Kuhli Loach Pangio kuhlii is an active, fascinating little fish. Its behaviors are typical of all members of the Pangio genus. It keeps in almost constant motion, actively scurrying around, over, and through the plants and ornamentation. It is scavenging for leftover foods that have settled on the bottom of the aquarium. This is a great little helper in keeping the aquarium clean and in good shape..
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, Leopard Loach, and Cinnamon Loach. Coolie Loaches are exported by the millions for the aquarium hobby.
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 term 'kuhli loach' is often used collectively to refer to a group fish in the Pangio genus (previously the Acanthophthalmus genus) that are much like the actual Kuhli Loach. These loaches all have the elongated wormlike body shape, are fairly similar in size and appearance, and are also wiggly little scavengers who make great aquarium cleaners. Each of these fish however, can be distinguished from the Kuhli Loach by their individual color patterns and adult size.
The Kuhli Loach Pangio kuhlii (previously Acanthophthalmus kuhlii) was described by Valenciennes in 1846. They are found in southeast Asia; Sumatra, Singapore, western Malaysia, Java, Borneo, and Thailand. This species is not listed on the IUCN Red List. Other common names they are known by include Prickly Eye, Coolie Loach, Giant Coolie Loach, Cinnamon Loach, and Leopard Loach.
They live in sandy areas of slow- moving rivers and mountain streams covered in leaf litter. Their habitats are normally shaded from the sun by the forests canopy. In nature these loaches are found in small groups, however they are not schooling fish.
Scientific Name: Pangio kuhlii
Social Grouping: Groups - Not actually schooling fish, but are usually found in clusters of their own kind.
IUCN Red List: NE - Not Evaluated or not listed
The Kuhli Loach is a smaller, worm-like loach that can reach from 3 - 4 1/2 inches (7.8 - 12 cm) in length, though generally a bit smaller in the aquarium. Their life span is generally about 10 years, though they been reported to live even longer.
This 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 fin is set very far back, and the anal fin is set at the end of the base of the dorsal fin.
Their is also an albino color form of this Loach, known as the Albino Kuhli Loach. This a bred color form, and it is not certain whether the Albino Kuhli Loach occurs naturally in the wild. But these would be highly visible animals, so beacons for predation.
Size of fish - inches: 4.7 inches (11.99 cm) - These fish can get up to about 4 1/2 inches (12 cm), though they are usually smaller in the aquarium.
Lifespan: 10 years - This fish generally has a lifespan of about 10 years, but has been reported to live longer.
Fish Keeping Difficulty
This loach can be hardy under the right conditions. They are not recommended for beginners because of their need for pristine water and having small body scales and no scales on the head. Reduced scales makes them more prone to disease and very sensitive to medications used to treat disease. Experience in treating scaleless fish is very important to be able to give your loach a healthy and long life. Do not try to introduce these fish into biologically immature tanks.
Aquarium Hardiness: Moderately hardy
Aquarist Experience Level: Intermediate
Foods 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.
Diet Type: Omnivore
Flake Food: Yes
Tablet / Pellet: Occasionally
Live foods (fishes, shrimps, worms): Some of Diet
Vegetable Food: Some of Diet
Meaty Food: Most of Diet
Feeding Frequency: Several feedings per day
The most important thing for these loaches is that they always have clean and well-oxygenated water. Frequent water changes of about 30% a week are needed for the Kuhli Loach. With your weekly water change make sure to vacuum the gravel to remove all excess food and waste, but It's best not to remove any bio film on rocks and decor. A magnet algae cleaner normally does a great job in keeping the viewing pane clear.
Water Changes: Weekly - 30%
The Kuhli Loach will swim mostly on the bottom of the aquarium, but at night these loaches will swim all over the tank. Never introduce this loach into a biological immature setup as these fish require pristine water. This fish will do well in a medium sized aquarium (ideally 20 gallons or so) with soft, slightly acidic water and subdued lighting. They need good water movement that provides plenty of oxygenation. The tank water should turnover at least 10-15 times per hour. An undergravel filter is a great choice for these fish as it creates high oxygen through out the tank as well as reducing the waste. Adding a canister filter or power head to the setup will make the proper current for this loach.
The decor with for fish is really up to personal taste, but the substrate needs to be a fine gravel or sand that does not have sharp edges. They will also enjoy a bit of peat moss spread over the substrate to simulate the natural mulm found in their native environment. Some smooth water-worn large rocks and stones should be scattered throughout along with a couple pieces of driftwood and some twisted roots will make a great place to retreat. These loaches are very inquisitive and like to explore so make sure to have a lot of caves and crevices. These fish can and will jump out of the tank if given the chance so make sure to have a tight fitting cover.
Minimum Tank Size: 20 gal (76 L)
Suitable for Nano Tank: Yes
Substrate Type: Sand/Gravel Mix
Lighting Needs: Low - subdued lighting
Temperature: 73.0 to 86.0° F (22.8 to 30.0° C) - Though best kept in the 70's, They can tolerate the low 80°s for a short period.
Range ph: 5.5-6.5
Hardness Range: 0 - 5 dGH
Water Movement: Moderate
Water Region: Bottom - These fish are mostly bottom dwellers but will swim in all areas of the tank at night.
This loach is 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. It is recommended that they be kept in small groups of at least 6 or more of its own kind.
Same species - conspecifics: Yes - Best kept in groups of 6 or more, if kept singly a Kuhli will seldom be seen.

Sex: Sexual differences
On mature males the first ray in the pectoral fin is branched and thickened. Adult females are typically heavier-bodied and a little larger then males. Female with eggs will also be plumper.
Breeding / Reproduction
Although they have been bred successfully in the aquarium, not much is known about the breeding habits of the Kuhli Loach. 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.
Ease of Breeding: Difficult
Loaches are more susceptible to disease than other aquarium fishes. This may have to do with the faint body scales and no head scales. So take caution when introducing these fish to an established tank. They are also very sensitive to different medications used to treat many diseases; a separate hospital tank is needed. Cold water and condition changes can also cause stress to this fish which makes them even more prone to disease.
Most common disease that affects this loach is Ich. Ich is short for Ichthyophthirius, also known as "white spot disease". It is a parasite that can attack nearly all aquarium fishes, but you'll find that loaches are often the first to be attacked. Take great care in treating ick as loaches are very sensitive to the medications used to treat it. Often the dose is half of what is normally used.
The second most common thing that affects loaches is a thing called skinny disease. This can be diagnosed fairly easily. If your loaches are eating a nitrous and healthy amounts and still seems to loose weight it is a good chance it has skinny disease. This is caused by internal parasites and can be treated with medication if used carefully.
An outbreak of disease can often be limited to just one or a few fishes if you deal with it at an early stage. When keeping these sensitive types of fish, it is common to catch deteriorating water conditions and disease before other fish are affected. The best way to proactively prevent disease is to give your Kuhli Loach the proper environment and give them a well balanced diet. The closer to their natural habitat the less stress the fish will have, making them healthier and happy. A stressed fish will is more likely to acquire disease.
Anything you add to your tank can bring disease to your tank. Not only other fish but plants, substrate, and decorations can harbor bacteria. Take great care and make sure to properly clean or quarantine anything that you add to an established tank so not to upset the balance. It is recommended to read up on the common tank diseases. Knowing the signs and catching and treating them early makes a huge difference. For information about freshwater fish diseases and illnesses, see Aquarium Fish Diseases and Treatments.
The Kuhli Loach is readily available at pet stores and online, and is moderately priced.
Danie X Harrison - 2016-04-30 I have 3 kuhli loaches which i purchased about a month ago, they were riddled with white spot but I treated them straight away an look great now, my tanks conditions is as good as I can get them and do regular water changes, well planted, with guppies and 2 bristlenose plecos plenty of hiding places.
I've Bearley seen them since I got them but today for the first time all 3 kuhli loaches have started to swim around the tank like mad for a good 10-15 minutes then two went back to hiding and one was out on its own resting for 5 minutes now hiding with them again, I'm not used to seeing them out during the day, are they unhappy as I might not have as many as I should as they are social creatures, are they a bit lonely, are they breeding, as I've typed this one has just come out in the open again just resting on the bogwood an another is hiding in the pile of slates (they love to hide here) I can see its tail any advice would be really appreciated thanks you for taking the time to read this x
Andrew - 2016-07-07 Yes Kuhli Loaches are very social creatures and they love to interact with eachother. Kuhli Loaches do better if they are in a minimum group of five or they will usually go into hiding and might even go into permanent hiding. I would suggest that you get two more, but you have to have at least a 10 gallon tank or they will be crowded. And one more thing your Kuhli loaches might also be hiding because you might have an aggresive fish in your tank. I hoped i helped you, and good luck with your loaches!!!
Connor - 2014-10-16 I have two community tanks and I have 4 kuhli loaches, two in one and two in the other. And in my main tank they come out all of the time but in my littler tank I hardly ever see them. They are gorgeous fish to keep and also they like to come out at night. These are lovely fish to have so I recommend you get these. If you know why my other khuli loaches don't come out please let me know?
Foxtrot - 2015-08-24 You need more loaches in both tanks! They tend to prefer groups of 5+, and the more there are, the more comfortable they will feel!
Gale - 2016-02-13 Hi...I love Kuhli Loaches. I originally started with 4 about 11 months ago & they were extremely hardy. Then I decided to get a few more. The pet only orders them three at a time so I purchased all three. Once those three were added I stopped seeing my Kuhlis as often as I did but low & behold a few months ago, two or three I discovered I had what appears several babies. I've tried to film them which is virtually impossible, they are too quick. I don't have sand in my tank. I have gravel & they are excellent at hurrying themselves. Honestly, I don't know how many Loaches are in my tank now but I'm so excited!
Maria Anderson - 2015-04-26 Hi, I'd very much like some feeding advice! I have three Corydoras aeneus and three Pangio kuhlii. The Cordy's absolutely throw themselves over the pellets and tablets that I give them twice a day, and there's really nothing left for the Kuhlii guys once they are done! The Kuhlii's come out from their hidingplaces every now and then, but they always comes out too late when it's feeding time! The Cory's has cleaned the plate, so to speak, and left nothing! And even if I see the Kuhlii's and try to make a tablet sink closeby to them, the Cory's are like missiles and eats that tablet too! How do I make sure that the Kuhlii's gets properly fed too?!!!
Clarice Brough - 2015-04-28 The Corydoras are simply more active, and they love to eat! Neither of these fish are aggressive, it's really about their natural activity levels. The Kuhlii are more reserved, as you've seen, so it may take a separate tank for each to make sure your Kuhlii don't end up starving.
Liam - 2015-02-24 Help, I have 2 Kuhli Loaches and I am keeping them in a medium tank with 4 guppies and a dwarf gourami. The two loaches seem to be floating on the surface of the water all the time and never seem to be able to stay at the bottom. The also have been climbing onto the suction cup of the heater and staying partially out of the water, they were doing this before they started floating. If anyone knows anything please help.
Clarice Brough - 2015-02-24 This does happen with Kuhli Loaches, and it's often related to tank conditions and water changes. They need soft, slightly acidic water with good movement so that there is also plenty of oxygen. They always have to have very clean water, and it helps if each partial water change is relatively small.
It's said that hardness changes due to new water can be one of the reasons they float. You need to know the pH and hardness of your tap water and of the water in your tank. Then the replacement water needs to be adjusted to have the same hardness as the tank water, to help avoid problems like osmotic shock. Hope this helps.
