Kuhli loaches are slender and snake-like, with many narrow dark bands or a near-solid dark form.

Visible differences
Clues to inspect
- Kuhli loaches are slender and snake-like, with many narrow dark bands or a near-solid dark form.
- Yoyo loaches have the deeper, laterally compressed body of a typical botiid and broad reticulated markings.
- Yoyos are visibly more robust and active in open water as they mature.
Shared traits
Why they are confused
- Both are social Asian bottom dwellers that use cover.
- Both need escape-safe aquariums and should not be kept singly.
Why it matters
Do not stop at the name
Yoyo loaches become larger and more assertive; kuhli loaches are shy crevice foragers with different companion needs.
Uncertainty
When a photo is not enough
Several Pangio species are sold as kuhli loaches. The broad care category may be more certain than exact species.
