Need tank stock help

[Oceangirl]

I currently now have 2 tanks set up,
Tank 1: 20 High
filter Penguin 150B
Stock 10-12 baby fish 1 inch or less in size
Substrate: Black sand

Tank 2: 29 gallon
Filter: Aquaclear 70
Substrate: Blue sand
Stock: 1 Peppered Cory (Rescue from a tin foil, being chased and fins eaten)
1 zygatus cory (sold as a "darker bronze cory")
4 Panda cories
2 Bronze Cories (My hubby rescued 1 from a lone tank by himself)
1 random unknown cory? he is VERY small (rescue from BAD tank)
5 platys (2 red wag, 2 sun burst, 1 panda)
2 mollies (1 gold dust, 1 black molly fry from a previous litter 1.2 inches)
1 breeder basket of Guppy fry
3 female guppies

Now, I think I might throw an adult platy or two in with the babies. They are big enough not to get eaten. I think I might be getting rid of the Gold dust molly because I read she gets 5 INCHES! though not sure if she is one. Plus they ( Mollies and Platys) seem to be eating ALL MY PLANTS! I am thinking keeping just my 1 panda, 1sunburst, and my 2 mollies till they get too big.
What do you think?

If you're going to keep the Pandas, keep all 4; Corys do best in groups of their own kind and can get very stressed if left alone or in insufficient numbers.

I was planning on maybe moving/ getting rid of the platy's to my 20 high. No way I'll give up any of my whiskered friends! They are addictive with their antics. They were chasing, puppy piling and chasing the other cories.
