How about:
6-10 Black skirt tetra (Gymnocorymbus sp.)
6-10 Red Minor tetra (Hyphessobrycon callistus)
6-10 Zebra danio (Danio rerio)
4-5 Platy (Xiphophorus maculatus)
6-8 peppered Corycatfish? (Corydoras paleatus)
1 bolivian ram? (Microgeophagus altispinosa)
Is that something that you would like?
I also got a question, Do you happen to know what gender platy you have? Since they are livebearers and are prolific breeders, You could have babies every few weeks. If you dont want any babies, I would advise to only have one gender (Female)
Also, As far as the bolivian ram in the stocking, They do need a well established tank (3-4 months after cycle) to thrive in the tank.
