Source-derived summary

Acheilognathus rhombeus is a temperate freshwater fish belonging to the family Acheilognathidae, the bitterlings. It originates in Japan and the Korean Peninsula. It was originally described as Capoeta rhombea by Temminck & Schlegel in 1846. It is the type species for the genus Acheilognathus.

When spawning, the females deposit their eggs inside bivalves, where they hatch and the young remain until they can swim.

Editorial summary

Begin with the source’s own compact description: “Acheilognathus rhombeus” is species of fish. The dossier treats that line as a proposition to test through Acheilognathus, rhombeus and species, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1846, 2007—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Acheilognathus, rhombeus and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

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 Q653066. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1846 and 2007.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. 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.
