Green Rili OE, developing F2 — original Orange Eye cross report

Identity and breeder

Neocaridina davidi (ornamental attribution) — Michael Häsler and collaborators

Published date and report type

2026 original report; First-person line-development account unless noted

Illustrated breeding family / evidence tree

Reported original source stock

Green OE stock with Rili-pattern-selective input; parents not explicitly documented

Reported actual crossing or selection sequence

Breeder reports growing second generation with Rili pattern hard to stabilize

Observed phenotype

Green-rili patches/translucence with orange eyes

What author claims

Authors estimate about 5–10% of current second-generation juveniles display Rili pattern

Measured brood counts

Approx. 5–10% estimate; brood numerator/denominator missing

What remains uncertain

Approximation is NOT a measured frequency or Mendelian penetrance; F2 not defined by identified mating pair

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.
