I have a 50 gallon tank with some mollies, couple of cories, an algea eater, 3 guppies and a dwarf gourami. Would really like to add a betta, but not sure how bettas do with dwarf gouramis. Will they fight since they are of the same species? Also, on that Melafix warning, dwarf gouramis are labyrinth fish I think....does that apply to them?
