Zebra Danios and Dwarf Gouramis?

Sorry, for some reason I couldn't respond to your pm. I think you could keep 4-6 of them with 2 or 3 grmis. I'm not much into the peacfull fish so I could be wrong.
 
I don't know if I would put more than one gourami in a 10g tank. They can be aggressive to their own kind and 10g isn't a lot of room for them to be away from each other. As far as danios and gouramis together, I have had no problems with that combination in any of my tanks.
