What Kinds of Tropical Fish are These?

[BakedFish]

To clarify, I know what species they are (guppy & molly) but I don't know what breed they are. Any help would be appreciated!
The fish I am talking about is the guppy and this grey molly. Both parents of the grey molly are almost fully black so I guess it's a mutated or recessed gene? I added photos of the parents (the big fishes)
