Overview
The yoyo loach is a lively, silvery fish crossed with dark bands and blotches, and it got its fun name from those markings. On young fish the pattern really can look like the letters Y-O-Y-O spelled across the body. As the fish grows the bands break up into a maze-like mesh, but the playful name stuck.
Yoyo loaches come from the slow rivers and streams of South Asia, including parts of India, Pakistan, and Nepal. They are busy, curious bottom-dwellers that love to root around the substrate and squeeze into caves. Aquarists prize them for one very handy habit: they are excellent snail hunters, using their downturned mouths and sensitive barbels to sniff out and eat pest snails that plague planted tanks.

A fish that spells its name
On young yoyo loaches the dark markings can look like the letters Y, O, Y, O running along the body. That eye-catching pattern is exactly where the name comes from.
Snail patrol
Yoyo loaches love to eat snails, making them popular for controlling pest snails in planted tanks. They use their barbels to find prey and their mouths to pull snails out of their shells.
Social and playful
These loaches are happiest in groups of five or more. Together they chase, tumble, and explore, and they even rest in funny piles. A lone loach tends to be shy and stressed.
Where it lives
It comes from the rivers and streams of South Asia, including India, Nepal, and Pakistan, favoring flowing water with rocks, roots, and plenty of nooks to explore.
Keeping it happy
Give it a soft substrate to dig in, caves and driftwood to hide among, and clean, well-oxygenated water. A secure lid helps, since active loaches can be escape artists.
