Stocking 60 litre (15 gallon) planted tank

Hi, I recently setup a new 60 litre tank and started planning stocking the tank.

The tank is most likely cycled by now since the filter media came from a mature system but I'm still willing to wait a few weeks to be certain it can support the bio load.

I ran all my ideas through Aqadviser and it seems it will work fine, but I've read some horror stories of people who tried to keep Corydoras with a Dwarf Gourami and I was wondering if anyone has any advice for me?

Can they be kept together or will there be fighting?

Also about the Dwarf Gourami:

I've kept some before in a 45 litre and never had any problems, so I was quite surprised to read up on their diseases.

All the ones at my lfs seems extremely healthy so I was wondering if the the South-African market was affected since I read the disease is associated with certain breeders.
