GUPPYPEDIA / SOURCE-REVIEWED STRAIN FAMILIES

Guppy strain families and breeder evidence

Six documented phenotype families; 36 linked guppy catalog labels, not 36 genetically verified bloodlines. Original-line pedigrees and commercial-name inheritance remain unverified unless noted.

Moscow

Genetics: Moscow coloration is historically described as strongly paternal/Y-associated in selected lines. That is not proof that every market variant has the same genotype; autosomal modifiers matter.

Breeder evidence: Colorz Guppy Farm described its Blue Moscow re-establishment and imported breeder stock in 2022; this is a dated maintenance program, NOT evidence Colorz created Moscow.

Breeder evidence: Source-scoped breeder record

Pedigree: Parent lines not documented. No asserted founder pair or invented arrows.

fin pattern6 catalog labels

Grass (Blue and Red)

Genetics: IKGH recognizes Grass as spotted fin pattern. Diana Walstad observed segregating Blue Grass, Red Grass and other males in her own selected colony; her results are not a universal commercial-line segregation rate.

Breeder evidence: Diana Walstad documents her own Blue Grass matings and Japan Blue cross. This is a firsthand observer/breeder report, not proof she originated Grass.

Breeder creator or maintainer not established for this family.

Pedigree: Parent lines not documented. No asserted founder pair or invented arrows.

body pattern3 catalog labels

Snakeskin / Cobra

Genetics: Controlled green/yellow Snakeskin crosses in Phang et al. 1989 reported sex-associated body/tail pattern factors; do not extrapolate those loci to untested commercial Snakeskin or Cobra stocks.

Breeder evidence: Stephen Neil Kwartler lists maintained Variegated Snakeskin and AOC Bicolor Cobra in his IFGA breeder advertisement; not evidence that he invented the Snakeskin family.

Pedigree: Parent lines not documented. No asserted founder pair or invented arrows.

metallic body color1 catalog labels

Japan Blue

Genetics: The IKGH standard describes a metallic blue posterior body; aquarist crosses and guppy genetic references document Y-associated examples, but that cannot establish an individual seller line's full genotype.

Breeder evidence: The Japanese geographic name is not necessarily evidence of an individual strain creator. Some Japanese wild populations show a similar blue trait; domesticated provenance needs its own records. An Endler-labeled Japan Blue entry is not counted as proven P. reticulata ancestry.

Breeder creator or maintainer not established for this family.

Pedigree: Parent lines not documented. No asserted founder pair or invented arrows.

body/fin color3 catalog labels

Full Red and Albino Full Red

Genetics: Full Red describes the coverage of red; an albino eye/body base may be layered with it. A uniform red appearance does not independently authenticate the underlying genotype or origin of a breeder line.

Breeder evidence: Stephen Neil Kwartler independently lists Full Reds among his maintained show-guppy lines; this is a self-reported stock category, not proof he created every Full Red variant.

Pedigree: Parent lines not documented. No asserted founder pair or invented arrows.

Koi / Tuxedo Koi

Genetics: Koi is a color and pattern trade umbrella; Koi Red Ear, Tuxedo Koi and short-body variants cannot be reduced to one proven Mendelian pedigree without controlled breeding records.

Breeder evidence: Colorz Guppy Farm named HB Tuxedo Koi in its 2022 breeding plan, while reporting separate imported guppy batches. This documents intended maintenance, not inventor or purity status.

Pedigree: Parent lines not documented. No asserted founder pair or invented arrows.

How to interpret the evidence

The categories are 2023 IKGH show descriptions or trade-family labels, not genetic strain registrations. Association credentials document a person's awards, not the creation of a specific color family. An importer or retailer may breed one variant but cannot be assumed to have invented the whole family. Parent lines not documented means no cross is inferred. The similarly named Japan Blue Endler catalog item is intentionally excluded from these guppy-only family links.
