I have not had the fortune to maintain any of the wild-type bettas, but I have kept Betta splendens for years (various individuals) in my planted tanks. I have never had a problem with them. Of course, I only kept one male and a couple of females together. Fish they have lived with included angelfish, cardinal tetras, threadfin rainbowfish, corydoras, rummynose tetras, otocinclus, pencilfish, and blue rams.
Many years ago, I even kept a male Betta splendens with a pair of discus. No problems whatsoever, and the Betta appreciated the 82F water.
