AQUAPEDIA / CORYDORASPEDIA
Strains, species and the evidence between.
The public research forum includes 528 historical specialist directory labels; this starter collection examines eight captive morphs and eleven documented breeding reports. Those numbers are not counts of verified species or genetic loci.
START EXPLORING
Three evidence-first paths.
Lineage & genetics atlas
Eight selected phenotypes, source-backed relationships, uncertain pedigree edges and show-result distinctions.
Breeding & fry feeding
Eleven named keeper reports; egg counts, feeding steps and cautious interpretations of tank conditions.
Scientific evidence desk
Eight source-linked research areas: taxonomy, habitats, reproduction, genetics, identification, welfare, conservation, and breeder history.
How we distinguish a lineage.
Documented selection: named keeper or dated specialist account describes breeding decisions. This does not prove a unique genetic locus.
Reported phenotype: an aquarium color or fin trait is observed. Founder and heritability may remain unknown.
Scientific species: a formal taxonomic name is separate from a C/CW hobby identification code and a domestic strain name.
Accepted names and historical labels
A hobby C/CW label is not a formal species name. The California Academy of Sciences lists the former Corydoras duplicareus as Hoplisoma duplicareum, and the former Corydoras weitzmani as Hoplisoma weitzmani (one final i). Original catalog labels are preserved for historical searching, not presented as separately valid species.
