There are a few other threads much like this one. I got a pair of Pearl Gouramis that were hanging out together in a tank of blue gouramis. My guess is I got one male and one female but the smaller one might just be a younger male. The larger one (not pictured) has a red chest and belly with a long dorsal fin. He wouldn't come out where I could get a good picture. The one pictured is a little smaller with a much smaller dorsal and barely in color on its belly. Opinions, boy or girl? They seem to get along and are always near each other.
