The public source identifies “Orthochromis” as genus of fishes. This brief keeps that definition visible, then builds a research path around Orthochromis, genus and fishes.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Orthochromis”, the useful work is to connect “genus of fishes” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q2704842. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1994, 1998, 1967 and 1937.
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
