My male usually left the female alone while she was pregnant. But, like keepingfish said, he would get a bit more aggressive towards her near the end of her pregnancy.
Mine on the first time stopped but then staterd again on around the 80 day mark resulted in her giving birth to early 2 died and 1 was batman ray . The male can realy stress the female out and make a mess of her disc i would keep a close eye on them . I would say she will be all ready preg so good luck with it !
