Funny. The male molly was talking about was a black one.
Unfortunately our Dalmatian male passed away unexpectedly from unknown causes. Our silver female had some sort of deficiency resulting in shakes, a curved spine, and difficulty swimming. she passed on her own while we were trying to correct her diet. We've had very good survival rates from the fry, all of which are the general orange molly. Their mother had to be put down because of an unknown illness though.
If you do want to get a molly or a few of them, be sure to get them from a good source. I'm sure you already know how to tell male from female due to your research, but always be prepared to have babies and a lot of them sometime within 3 months of buying a female. they're pretty much guaranteed pregnant when you buy them since they don't separate genders.
Mollies are also not such a good community fish. They harass a lot regardless of gender (Males more so though) and they do produce an ungodly amount of waste for a fish their size.
Platys however have some more spunk tot hem and do well with bettas. Raised a fry in our sorority tank and she acted like one of the girls. They do eat live plants, but nowhere near as bad as a molly does and they can make quite a mess. Overall, I think a platy or a group of them along with a sorority would be very good together as well as entertaining for you.
