Yoyo loach
The yoyo loach, Almora loach or Pakistani loach is a freshwater fish belonging to the loach family Botiidae.

It may attain a length of, and is named for its dark and pale patterns, which often can be seen to spell "yoyo", hence the common name yoyo loach. The final common name, Almora loach, refers to Almora in Uttarakhand, India. Specimens labelled as B. almorhae are commonly found in the aquarium trade, but most of these appear to be the closely related B. lohachata, two possibly undescribed species popularly referred to as B. sp. "Kosi" and B. sp. "Teesta", or hybrids.
