The yoyo loach gets its name from the twisted stripes along its flanks. They seem to spell out the word "yo yo," making them an instant aquarium favorite. Yoyo loaches are also active and undemanding pets that are a good addition for most community tanks.

What is the Yoyo Loach?
Yoyo loaches are better thought of as a species complex: a group of different species that are all close relatives. That's why there is a lot of confusion when you look for information about the yoyo loach.
Even the scientific name and origin gets difficult. Botia almorhae is the yoyo loach you most often encounter in pet stores.
All of the species come from Pakistan, North India, and Nepal. They also have identical care requirements. So it's not super important to sort out which kind of yoyo loach you have.
Yoyo loaches are one of the smallest members of the family Botiidae. There are several members of the group that are regular additions to the aquarium hobby. But the yoyo loach is one of the most popular; only the clown loach is more common.
