My betta Charlie passed away this morning. So now my 10 gallon tank seems empty. There are 6 pygmy corys in the tank right now with a few snails. I was wondering if two dwarf gouramis be ok in a 10 gallon tank? There are some female and male dwarf gouramis at work that I'm interested in getting. I was thinking of getting either a pair of dwarf gouramis, another betta fish, or a few guppys (maybe 3 or 4).
