Harlequin Gold fits. Could be an oddball gold nugget mixed with a gold dust too, mixes have no proper names. lol
The "Silver" one could indeed be a green molly. Looks like one. I had forgotten about those, only seen them once. Some come out like yours, others come out darker or even sorta spotted. Many of the lighter ones do have a bit of yellow on them, especially around the belly, tail, or chest.
Silver mollies are typically white and stay there. They're properly called White Mollies though. Sometimes you get silvery-grey ones mixed in there that fit the name. I have some real silver mollies.
Basically aside from the male that may in fact be a green sailfin, your other is likely a mix, and knowing what mix will be nigh impossible, some mixed mollies can come with a rather large assortment of colors even if the parents didn't carry them. Especially if they're second or third generation mixes.
These are some of my mixes. In this photo you can see a silver(or white molly which was mom) mixed with a short finned molly, and some silver dalmations. They are not white like mom, but are true silver like dad though they lack the yellow he had on his tail and belly. The pale orange and black one is a wild short-fin molly mixed with a creamsicle. The pretty cream colored one on the very bottom with orange spots and the nice sail is a creamsicle mixed with a silver sailfin.
A creamsicle short-fin mix(see why I thought yours might be one except mine has more black):
Here are a couple different green mollies via google and not my own collection: http://www.fishlinkworldwide.com/fis...n_sf_molly.jpg http://easytospot.blogs.com/.a/6a00d...181ef6f970b-pi http://goliadfarms.com/wp-content/up...lfin_male1.gif
