I stocked FHM and GSH a year ago. I hand fed and then installed feeder. There have been no predators up to a month ago. I saw my forage fish all the time in the shallows. They cruise the edges in good sized flotillas. With dark water and bottom, they are hard to spot sometimes. Put something light on the bottom and you can really seem them cross over it.

When food it out, they are there quickly. Can have a dozen around every pellet on the surface. Stocked bass were only 3", but I haven't seen any significant change in behavior yet.
