Hi Ricky,
Pls turn off the caps lock.:wink2: This may seem a bit like shouting.
You can't cross mollies and swordtails but you can cross swordtails with platies.:wink2: I have discussed this already in a few threads.
Platies(Xiphophorus maculatus)+Swordtails(Xiphophorus helleri)=Variegated Platy(Xiphophorus variatus)
