That could be true. Like I've already mentioned, the sperm packets used are random.I'm pretty sure the batch of guppy fry I'm rearing now have two fathers. I'm 80% the female was virgin, a blonde female, only exposed to a yellow snakeskin male, and a half black blue male. Half the fry are yellow, half are grey, starting to develop their black and some colour. I'm pretty convinced both males were the fathers here.
