I'm confused

[maddie]

Hi,
I have just started breeding Mollie's & Swordtails and in the confusion of sorting out tanks I mixed them up. I know it sounds dumb but I'm having trouble identifying betweem some of them. The body shape of the younger ones (or smaller) seem to be very alike and also their dorsal fin seem similar.
I don't want to cross breed because the fry are being sold to the local aquarium.
Any suggestions will be very welcome.
Regards
Madeleine
