I had a black male molly that acted like that. He had his chosen female and wouldn't let any other fish (male OR female) near her. Another female would try to swim with her (a BFF chic thing lol) and he would chase her away. I've even seen him pin "his" female against the side of the tank to keep others away from her. Reminded me of an overbearing husband that refuses to let his woman have any friends. He would occasionally try to mate with other females but NO ONE got close to "his" girl! I finally had to trade him off because he became so aggressive.
