The only answer I can gice you is yes if they feel like it. I tryed every trick in the book when I first started keeping them but nothing ..Then moved then to a smaller tank on their own while doing some re-arrangments and one week later..babies!..Once they start you need never worry about triggers again as they just dont stop
It worked for me but could have been just one of those things. The best tip I can give you is make sure the male has a cave of some sort. Mine use a cichlid spawing cave the same as the one in this link
