10 gallon idea............

pygmy corydoras would be perfect for a 10 gallon tank, and you could have four of them along with the dwarf gourami and 2 platies.
I would say 6, they only get an inch long as adults.

you could have 1 ram and 6 dwarf cories, or a DG and 2 platies.
 
would the DG and platies be with dwarf corys?
yes, i'm just sayiong if you still want a ram you can get 1, but it will be the only thing you can have other than dwarf cories.
 
you should fishless cycle your tank first, then add the platies, then the dwarf gourami, and then the pygmy corydoras. if you cannot find any in any LFSs around you, then you may have to have them order them for you.

if you carry out 25% water changes every week and do not overfeed you should be fine.
