About
Native to fast-moving rivers across Pakistan, India, and Nepal, yoyo loaches have earned a devoted following in the hobby for good reason. Their reticulated black-and-white pattern does loosely spell out 'Y-O-Y-O' when the fish is young, though the markings become more maze-like as they mature. Adults can reach around 15cm, which surprises a lot of keepers who bought them as tiny juveniles barely pushing 5cm in the store.
These are social, boisterous fish that spend a lot of time interacting with each other and exploring the tank. You'll regularly catch them mock-chasing, piling on top of one another under driftwood, or lying completely motionless on their sides on the substrate. That last behavior can genuinely alarm new keepers, but it's completely normal. They're active during the day, which sets them apart from a lot of other loach species that stay hidden until lights go out.
Water-wise, they do best in slightly soft to moderately hard water with a neutral to slightly acidic pH. Good filtration and decent flow matter more than hitting exact parameter targets, since they come from rivers with solid oxygenation. A fine substrate is appreciated since they'll nose around the bottom constantly looking for food.
They're genuine omnivores and will accept sinking pellets, frozen bloodworm, brine shrimp, and even blanched vegetables. Their snail-eating reputation is very well earned. A moderate infestation of bladder or ramshorn snails can disappear within days of introducing a small group.

Keeping multiple Yoyo Loach together
Yoyo Loach are shoaling fish and need company of their own kind. Keep a group of at least 5. Smaller groups leave them stressed, washed-out in color, and prone to hiding.
Compatibility
Yoyo loaches work well in community tanks with robust, similarly sized fish. Good pairings include large tetras like Congo tetras, barbs like tiger or rosy barbs, rainbowfish, and most medium cichlids that aren't actively territorial. Avoid anything with long flowing fins like bettas or fancy guppies, since nipping is a real risk. Dwarf shrimp are not safe regardless of tank size, the loaches will hunt and eat them. Ornamental snails will also disappear. Cory catfish can work as bottom companions in large tanks, but competition for space should be monitored. Aim for at least 200 liters when mixing with other bottom-dwelling species.

Often paired, but shouldn't beCare Notes
The biggest mistake beginners make is underestimating adult size and buying too few. A pair in a 75-liter tank is a recipe for stressed, aggressive fish with nowhere to go. They need space, flow, and a soft substrate that won't damage their sensitive barbels. Bare bottom tanks or coarse gravel are a bad fit. Sharp decor should also be avoided since they're fast-moving and prone to scraping themselves. Pristine water quality matters more than perfect parameters, so consistent water changes and good mechanical filtration should be the priority. Overfeeding is also common since they always seem hungry.
Behavior & Aggression
Yoyo loaches aren't aggressive in a dangerous sense, but they're not entirely peaceful either. Most of their aggression is intraspecific, playing out as chasing and minor scrapping within the group. Keeping fewer than five tends to concentrate this behavior on one or two individuals, which can cause stress. In larger groups the dynamic spreads out and nobody gets singled out. Toward other species they're mostly fine, though they can pester smaller, slower fish and have been known to nip long-finned tankmates during feeding time, especially in crowded conditions.
Things to Know
- Grows to 15cm+, often sold as juveniles at 4-5cm. Plan tank size accordingly.
- Will eat all snails, including pest and ornamental species.
- Will eat dwarf shrimp and small shrimp of any kind.
- Playing dead is normal behavior, don't panic if you find one on its side.
- Keep in groups of 5+ or aggression within the group becomes an issue.
