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 the Black-Lined Loach 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 Horseface 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 .
The Myer's Loach will swim mostly on the bottom of the aquarium, but at night these loaches may 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.

Example: I have there some halved clay pots all over my aquarium that would easily fit all my clown loaches. They never use them. They are always found in the smaller cichlid caves with the tiny openings.
Aquarium Fish Magazine: The Loaches
To keep a school of dwarf loaches happy and healthy, their aquarium will need to be set up to reflect their natural habitat. The dwarf loach will need plenty of open space for schooling. The dwarf loach doesn't necessarily need any hiding places, since it is active and visible most of the time. However, the dwarf loach will still prefer some places in which to rest when it's not swimming. Rocks, roots, driftwood, plants and pipes make ideal places for the dwarf loach to rest. When the dwarf loach has plenty of broad leaved plants, the loach will often rest on one of the leaves instead of going into hiding. In fact, the dwarf loach prefers to rest on plant leaves instead of the tank's substrate.
