Dwarf gouramis are good fish for a 10 gal but dont do 2 males together. Make it a pair of male and female or 2 females because 2 males will fight and you can add a school of 5 neon tetras and still have a room for a little more fish but try not to over stock. Im getting a male and female dwarf gourami for my 10 gal as well. Theirs diff colors you should take a look at them their pretty easy to take care of.
