Ok I am not going to flame you yet but do you have a pond or atleast a 12x6x5 tank? If you don't SHAME ON YOU! What are you doing with the fish afterwards? Anyways JAgs do this all the time it's just a behavior that most cichlids have. It is to make there home more suitable for them selfs such as easier entrances into caves and stuff like that. I am sure your jag does not want to mate with catfish, pbass or a GT and the mayan I am going to say no but possible. This not really a characteristic of many guapote to do when mating as they already have the habit anyway.
