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 Sapphire OE background and Dark Green Jade source family
Reported actual crossing or selection sequence
Crossed Black Sapphire OE into Dark Green Jade, then backcrossed promising green OE descendant to Dark Green Jade
Observed phenotype
Green body with bright orange eyes
What author claims
Breeder interview reports a SINGLE small green OE male (3–5 mm), which survived and was used to stabilize green backcross lines
Measured brood counts
One target individual reported; no total cohort
What remains uncertain
Single reported selected founder candidate is not proof all worldwide Green Demon stock descends from him or that green is single recessive trait
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.
