Trying to work out parentage

[BillBixby]

I've got two pretty little guppy juveniles at the moment but I'm trying to work out who their likely parents are.

I've got yellow tail guppies (3x female, 1x male) and orange guppies (2x female, 2x male) and 1 Japanese Blue (1x male).

The juveniles are pale yellow with dark spots on the tail. I THINK it is most likely they come from a female yellow tail and the male Japanese blue. Any other opinions? Some pictures of them all included.

You may not know, guppies can store sperm for up to a year from any male theyve bred with, so even if they bred at a store, there's a chance a store male could be the father of these too.

The problem overhere, is that you also don´t know what the genetic background of all your guppies are. If one or more of the adults already come from a mixed line, than even one of those red males could be the father. Or it concerns used sperm packets from a former mating before you´ve got those females. Which makes none of the present males the father.

you can always 23+me (other genetic tests are available) the whole tank to see who are related
