I managed to snag 4 wild caught dwarf gouramis from my LFS a few months ago. Originally I thought 3 of the 4 were females because of how subtle the coloring was, but a few weeks later they colored up and 2 were actually males. Now I have 3 males and 1 female, however they have been living peacefully without any issues a lot like honey gouramis. Upon observation they are much smaller(1.5 inches) than the farm raised ones. They're also much more peaceful and shy, and are very inquisitive. Here is a male and female pair.
