Hey, I used to have betta fish. Have you ever had one?
I have! I loved the ones that I had in my aquarium, because I was specifically looking for a freshwater ray-finned fish,and these were part of the gourami family, so they were very colorful. 
Oh cool. I didn't know they were from the gourami family. I think I remember something about them eating mosquito larva in rice paddies where theyre from.
Yeah, they're interesting little guys. They spawn in two different ways, either through bubble nests, like the B.Splendens, or through being a mouthbrooder, like the B.picta, if you want specific examples. They're quite unique!
