He will more than likely be protecting the place he chose to mate in,maybe a cave,,log etc, take this out for a couple of days then replace it in a new position in the tank , they can be very fiesty fish in spawning mode.
Taking out the feature takes away his chosen place,,Hence he has nothing to protect
but during his next spawning period he will start all over again so repeat this if he does.
sometimes doing this can change the pecking order in the tank, that is if another fish gets the cave before him this can have a calming effect.
