RESEARCH / EVIDENCE
A source-linked overview of what science establishes and what Aquapedia still needs to verify. This is a research draft; the eight topics are not additional verified species or pedigrees.
VERIFIED scientific revision
A 2024 phylogenomic analysis supports seven Corydoradinae genera, while the 2025 correction adjusts some species-name endings.
What this does not establish: C- and CW-numbers are historical provisional reference labels, not automatic species names. Individual code-to-species mappings require specimen-level cross-checking.
VERIFIED type records
Species descriptions and museum records can document type localities, including river drainage, watershed and specimen identifiers.
What this does not establish: A holotype locality is not evidence of the capture location or water parameters for every fish sold under that name.
VERIFIED in tested species
The sperm-drinking and pelvic-fin egg-pouch mechanism was reported in the species then known as Corydoras aeneus.
What this does not establish: Do not generalize the mechanism, incubation period, fry survival rate or spawning trigger to every related taxon.
VERIFIED behavior; loci unresolved
A study of 288 bronze corys across 36 shoals found pigmentation-associated behavior differences under the tested conditions.
What this does not establish: This experiment does not establish color alleles, Mendelian dominance, pedigrees or hybrid parents in domestic Corydoras lines.
VERIFIED evolutionary research
Published work describes Mullerian mimicry involving Corydoradinae; species can resemble one another without being identical taxa.
What this does not establish: Color-pattern similarity cannot by itself prove species identification or genetic ancestry; diagnostic vouchers remain needed.
VERIFIED sampled catfish tissues
Research documented venom-associated spine structures in catfishes, supporting careful handling of sharp dorsal and pectoral fin spines.
What this does not establish: The study cannot prove all Corydoradinae are equally venomous or that every barbel injury is caused by substrate alone.
Historical assessment; current status needs check
A 2016 published assessment documented conservation concerns about panda corys; current status and national collection/export rules require dated checks.
What this does not establish: A dated Red List assessment is not a fresh 2026 population survey or proof a particular import is lawful.
REPORTED named accounts
The ScotCat bibliography collects named breeder observations and species-specific spawning reports.
What this does not establish: A successful aquarium spawn is not proof of the world's first breeder, a new hereditary strain, or permission to copy the accompanying photographs.
Selected examples following the 2024/2025 classification; scientific names are not domestic breeding lines. Historical synonyms remain searchable. Verify any ambiguous entry against the current catalog before publication.

Verified: a specific primary source supports the described claim, with no automatic extension to other species.
Reported: a named observer documents a spawning or breeding practice; broader validation is pending.
Unresolved: genetic causes, founding stock, type identity or modern conservation status need additional sources.
For captive varieties, a true pedigree diagram requires documented parents. Otherwise, show Parent lines not documented. For wild species, use taxonomic relationships rather than invented parentage.
