Original evidence / species identification
Species-vouchered Japanese wild population descriptions must not be equated with market-colored morphs.
Illustrated research / ancestry evidence
Other taxonomic treatments
2021 lab study measured substrate choice across red/brown/white N. davidi; 2026 behavior pedigree counted 1191 individuals; 2026 pigment expression measured pathways in separately named denticulata specimens.
Contradictions and unresolved claims
None supplies a fully genotyped Red Cherry/Bloody Mary/Blue Dream/Orange Eye F1/F2 founder tree.
Ecological and breeder-pedigree limits
Aquarium releases into the wild create invasive risks; never suggest release or wild translocations.
Recorded commercial founders
Not documented in cited field taxonomy
Published, counted named-color F1/F2 ratios
No controlled commercial color F1/F2 segregation table in cited source
Primary scientific and database references
- Shih, Cai, Niwa, Yoshigou & Nakahara (2024), integrative identification of Neocaridina in Kyushu and Honshu
Peer-reviewed original field specimens, morphology and COI. Eight species / provisional lineages detected locally, not aquarium commercial founder certificates
- 2021 N. davidi background color preference controlled trial
Peer-reviewed captive-selected red/brown/white morph comparison. Color variation and backdrop response do not diagnose field taxon or one eye/body-color allele
- Neocaridina davidi 2026 known-pedigree behavioral genetics experiment
Peer-reviewed quantitative genetics, 1,191 offspring. Experimental offspring counted for behavior, not F1/F2 commercial color or speciation
- 2026 Neocaridina denticulata pigment gene expression and tissues
Peer-reviewed molecular gene expression. Different species naming in literature and measured expression are NOT confirmation of commercial single-locus dominant Cherry/OE color variants
