Ok. I wouldn't try it with those true short fin fighters (can't remember the name... plakat?) .I'm inclined to believe HarleyK's over yours. Some fancy females do shows some male characteristics and I've seen few fancy males that resembles a female. I checked out few videos on YouTube about keeping males together and it appears its extremely rare to keep them together without fighting. There is a video that has multiple males with angelfish but the video loader used lot of currents to prevent the males fighting each other. These bettas appears to not enjoying the currents.
