The FHM males showed zero interest in the plywood which from what ive read is a pretty popular FHM breeding spot in a pond setting. I had one male that show interest in one small over hang from a rock, he even moved around the gravel below it into almost a bowl shape, he stayed in his spot for over a week. maybe I didnt give them enough time. Although the current setup is easier to feed them and not as much clutter so im hoping for the best.
