Identity and breeder
Neocaridina davidi (ornamental attribution) — Michael Häsler
Published date and report type
2026 original report; First-person line-development account unless noted
Illustrated breeding family / evidence tree
Reported original source stock
Black Rose OE selected for rust-red patches plus Red Onyx commercial stock
Reported actual crossing or selection sequence
Multiple generations selected Black Rose OE for rusty red, then crossed into Red Onyx to strengthen body hue
Observed phenotype
Rust/dark red body with orange eyes
What author claims
Breeders report stable appearance similar to regular-eyed Red Onyx, apart from orange eyes
Measured brood counts
Not published
What remains uncertain
A documented multistage breeding approach without precise F1/F2 or parental sex data; dark-to-red color change not evidence of one-locus dominance
Care, selection, authentication
Maintain lineage-specific stock labels, isolate genuine known mating pairs in a matured tank, document sex and source of each parent, hatch-date cohorts and scored F1/F2 offspring. Color and orange eye often segregate differently in breeder accounts. Record water parameters rather than assuming one eye-color gene governs body color.
