Observed breeder-reported cross2010–2016
Two Blue Moscow lines and selection cross
Author or breeder: Igor Dusanic
Reported source stock and parent lines: Line 1 Hawaiian Moscow × Shubel Full Blue Delta, developed c.2010; supplemented with Hawaiian Moscow in 2015. Line 2 Blue/Green Moscow imported from Russia. In 2016 he reported Line 1 male × Line 2 female after three generations of selection.
What was actually observed: The breeder reported blue, dark blue, black, purple, green and dark green offspring. Selected purple males were returned to Line 1 females and green males to Line 2 females.
Limits: This does not establish Igor as the inventor of all Moscows, or certify today's offspring genetics. Family identity and imported Russian founders are self-reported; no independently numbered fish or verification assay.
Review note: Observed cross and line-maintenance account; breeder-authored, no third-party pedigree audit.

Observed breeder-reported cross2015–2018
Japan Blue × red tail, followed by Albino Full Red females
Author or breeder: A. Mtz. / Guppy México
Reported source stock and parent lines: Japan Blue males × ordinary red short-tail females; in a later pairing, Japan Blue males × Albino Full Red (AFR) females. A further cross used Japan Blue males and Red Mosaic females.
What was actually observed: First pairing produced F1 males with blue caudal-peduncle and red fins, according to the breeder. The later AFR-female pairing yielded 15 fry; 11 survived to adulthood. The breeder said fin quality improved but was still being selected.
Limits: The 15 fry and 11 survivors are a single reported cohort, not a universal hatch or survival percentage. These are not the original worldwide founder crosses of Japan Blue or Full Red.
Review note: First-person Spanish-language 2018 reports; exact F1/F2 pedigree IDs and independent genomic validation absent.

Breeder-proposed cross, offspring not verified2012
Albino Full Red × Milk Chocolate Moscow outcross
Author or breeder: Wee Yap / GuppyRealm
Reported source stock and parent lines: Reported Taiwan-origin AFR stock × maintained Milk Chocolate Moscow; the author listed A male × M female and a reciprocal notation written M male × A male.
What was actually observed: The author described an outcross setup and predicted grey-eyed offspring, but did not report a scored F1 generation, precise brood count, or verified genotype in this post.
Limits: The original source has a male × male notation for the supposed reciprocal cross, so its second parental direction is ambiguous. This is not proof of resulting offspring or a strain-creation event.
Review note: Breeder-authored planned experiment. Exact sex notation needs original author clarification.

Imported stock provenance2018
Documented Blue Grass acquisition from Japan through Taiwan
Author or breeder: Tim Herrmann / Guppy Hochzucht Berlin
Reported source stock and parent lines: A gray-base Blue Grass show-strain pair advertised by Taiwanese breeder Gary Lee as originally from Japan, obtained by Tim Herrmann at the Hasselt show through Tobias Bernsee.
What was actually observed: Tim Herrmann described receiving a male–female pair and intending to develop his own line from them, observing a fine spotted Grass pattern and dorsal shape.
Limits: A stocklist origin claim is not proof of the original breeder or founder mating. The post does not establish an F1 crop or the genetics of any later Tim Herrmann Grass stock.
Review note: First-person acquisition report with distributor's origin claim. No reproduced copyrighted photograph.

Retrospective history, genetics unconfirmed2020 retrospective
Grass versus Glass terminology and late-1980s Japanese lines
Author or breeder: Yoshiki Tsutsui / historical recollection
Reported source stock and parent lines: Tsutsui recalls circa-1970 imported Glass tails, later Grass labels, and a Blue Grass line associated with Yutaka Kishima in Kanagawa in the late 1980s.
What was actually observed: The writer distinguishes historical Glass from Grass naming and discusses his own phenotype/genetics hypotheses, including an informal 'He' designation.
Limits: This is a historical first-person recollection, not a dated generation-by-generation Kishima parentage ledger, genetic locus verification, or proof that Grass has only one origin.
Review note: Japanese-language reflective account; inventor attribution and ad hoc gene labels are unconfirmed.

Published plan only, no recorded pair2022
Half Black Tuxedo Koi breeding program
Author or breeder: Colorz Guppy Farm / Denny
Reported source stock and parent lines: The farm listed HB Tuxedo Koi, Blue Moscow, HB Blue and Red Dragon as 2022 breeding-focus strains, and separately described imported batches.
What was actually observed: Documented breeder program intention, not a published F1 mating or counted offspring. The author said Blue Moscow stock was being reacquired following losses in 2021.
Limits: There is no recorded pair, founder genotype or generation history for Koi in the cited program; neither importer status nor future plans establish inventor credit.
Review note: First-person dated program/merchant evidence; distinguish intended breeding from observed crosses.
