Should I be concerned. The water in this pond is not very clear except on the edges. When I first started feeding, I was getting the FHM to feed on the pellets pretty good ( some RES too) that went on 2 weeks. I have not seen any minnows or fish in a week, they quit eating pellets. I feed every day, now around dark, I do see activity in the middle of the pond. Looks like top water feeding. I did have a large cricket hatch in the last week. But not seeing any minnows has me concerned. I would have thought that feeding would be getting better not just shut off. No floating fish or minnows. Could it be they just have plenty to eat for now without pellets?
