So over the last 4-5 days I haven't seen my adult FHM coming to the surface to feed. I see fry everywhere, but I haven't seen the action from the adults like I usually do. The nights have been cooling down recently, is this normal for them to not come up and feed. I usually only feed 2-3 days per week and usually near dusk. I have tried feeding midday, but no luck seeing the adults. How often should I be feeding and is this normal behavior not to see them?
