Breeder-reported development2012–2022
Bicolor Moscow-derived selections
Named researcher/breeder: Stephen Neil Kwartler
Observed or reported: The breeder says he acquired a Bicolor Moscow strain in 2012, developed Blue-Green Bicolor and Blue-Green Grass from that stock, and showed a resulting Multi that took runner-up in 2022. No individually identified parents or published offspring ledger accompanies this self-report.
Evidence limitations: This is not evidence that the breeder created the original worldwide Moscow or Grass families; a self-reported show result is not independently linked here to the exact fish.

Maintained line (self-report)Undated first-person description
Reported true-breeding Full Red and Half Black Red
Named researcher/breeder: Stephen Neil Kwartler
Observed or reported: The breeder describes maintaining a true-breeding Full Red line as well as Half Black Reds among his long-maintained strains.
Evidence limitations: This is not an audited offspring percentage or confirmation of an original creator, genotype, exact generation or current stock.

Historic stock recovery2021–2022
Blue Moscow breeding-program restart
Named researcher/breeder: Colorz Guppy Farm / Denny
Observed or reported: A 2022 first-person entry reports losing most of the breeder's crossed-out Blue Moscow stock in 2021, acquiring new Moscow fish to restart the program and importing pairs until home-bred stock could be offered.
Evidence limitations: This is not a verified ancestral pedigree, indication of founder creation, or proof that 2022 importers and current offerings share a fixed line.

Planned breeding program only2022
Half Black Tuxedo Koi program proposed in 2022
Named researcher/breeder: Colorz Guppy Farm / Denny
Observed or reported: The breeder's dated 2022 priority list named HB Tuxedo Koi along with Blue Moscow, HB Blue Tuxedo and Red Dragon as intended focus lines.
Evidence limitations: A planned program is not evidence of a completed Koi cross, measurable offspring quality, stable transmission or creation of the global Koi family.

Scientific controlled cross2007
Pink/Moscow inheritance in controlled crosses
Named researcher/breeder: Michael Kempkes (researcher)
Observed or reported: The peer-reviewed Pink/Moscow × Pauper, reciprocal and related crosses in Table 4 support Y-linked Moscow coloration and autosomal-recessive Pink body color in the studied domestic lines. Table 4 includes measured F1/F2 and backcross phenotypes, not a blanket inheritance law for every shop strain.
Evidence limitations: These experimental results are not a genotype report for Blue Moscow retailers, a pedigree from the researcher to any named seller, or an authenticated creator claim.

Firsthand observed mating2017, reported May 2023
Japan Blue × Blue Grass observed offspring
Named researcher/breeder: Diana Walstad
Observed or reported: The documented 2017 Japan Blue male × Blue Grass female yielded F1 males combining the sire's iridescent body color and the dam's Grass tail morphology; additional matings are described separately in the full documented-cross atlas.
Evidence limitations: The experimental observations are not verified original founder stock for Grass, all Japan Blue commercial lines, or guaranteed offspring percentages.
