As works towards famous yet elusive Polish Pink Guppy progress I have some interesting variegated phenotypes appeared.
Shining factors marks on peduncle and tail fin seems to me to show relation between guanophores and melanophores within Var expression.
Appearance of variegation within phenotype seems to vary greatly. There are many factors which influence this subtle guanophores-melanophores relations. Yet some seems to be especially useful from breeder perspective. Main one seems to be full body modifiers like Y-linked moscow or Y-linked schimmelpfennig. Above shimmelpfennig males are still X-linked moscow Var.
As a bonus – here is a photo of one of the first so called Grass guppies.
