I agree. Once you go livebearers it restricts you completely.
Substrate fish you could look at are as follow:
Bronze Cory Catfish
Panda Cory Catfish
Dwarf Otto (Otocinclus)
Basically any small species of Cory under 3" (some get bigger). Ottos only for heavy planted tanks with enough algae too eat. Corys are a better bet.
If you go to your LFS or PetSmart or one of those stores....you can ask them about their fish. Most stores will keep MOST of their fish some how in the same water. PetSmart here keeps all their fish in fairly hard water and the Blue Rams and Bolivian Rams are bred in fairly hard water.
You should check this outbecause it will expand the option of fish you can keep in your tank.
Edit: I don't have any male platys (only females....and 20 fry who aren't big enough to sex yet)...but my male mollies are bred fighters. I can only keep one in a tank...I have already separated all my mollies so I only have one molly per tank. Males are vicious little things. I don't know about platys but if you want peaceful fish and not a lot of babies being pumped out every month...by the hundreds...go with only females.
