I am seeing the exact same thing as Don. My pond is full of FHM. Mostly from some I stocked last summer. The YP or RES haven't put a dent in them. The banks are thick with them, and even out in have middle when I'm in the canoe or swimming there are FHM everywhere. I have them both hitting the feed when the feeder goes off.
My visibility was around 3' a few days ago. SMB going in this fall. I suspect they will hit the FHM. If not, HBG...

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
