Source-derived summary

The yoyo loach, Almora loach or Pakistani loach (Botia almorhae) is a freshwater fish belonging to the loach family Botiidae. It originates in the slow-running and still waters of the Ganges basin in northern India and possibly Nepal. Despite the alternative common name Pakistani loach, the true B. almorhae is not known from Pakistan (the species in this country is B. birdi).

It may attain a length of 14–16 cm (5.5–6.3 in), and is named for its dark and pale patterns, which often can be seen to spell "yoyo" (especially in smaller/younger specimens), 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 (if not all) 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.

Editorial summary

“Yoyo loach” enters the record as species of fish. Crown Archives preserves that source wording while asking what Yoyo, loach and species can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 171-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Yoyo, loach and species.
Editorial analysis

Why this record matters

“Yoyo loach” is worth following because a concise public description often conceals a longer documentary argument. Here, Yoyo, loach and species provides the most credible route into that argument.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q1802036. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
