High Quality Content by WIKIPEDIA articles! A yoyo loach, almora loach or Pakistani loach, Botia almorhae, is a freshwater fish belonging to the loach family (Cobitidae). It originates in the slow-running and still waters of India and Pakistan, whence the name Pakistani loach originates. It is commonly found in aquariums, but is not nearly as common as its more popular relative, the clown loach. They may attain a length of up to 13 cm (5 in), and are named for their black and white patterns, which often can be seen to spell "yoyo" (especially in smaller/younger specimens), hence the common name yoyo loach.
