I was at the lfs here and they had a few more gray dwarf gouramis, and asked if they were female, as I was wanting a male and a female dwarf red gourami, but they said they were male blue ones, and that they aren't able to get females, as well as other specialty fish or snails. Might ask them if they can get females.
There dorsal fins dont look different, but im pretty sure one is a female because she has a round tummy, I looked it up, and only the females have that.
