Calvin, I stocked RES fingerlings into my new pond 9 weeks ago. The only other fish I have are FH and there's plenty of them. I kept some of the RES in an aquarium for a few weeks before stocking them so I know they averaged 1 1/4 inches long. I've been observing them in the shallow areas and they have grown quite a bit. The largest ones look to be almost 3 inches long and I would say they average 2 1/2 inches.

When I stocked the RES the FH were spawning so there was a lot of fry for them to eat. I was still seeing newly hatched fry until maybe two weeks ago, so the RES started out with as much food as they could eat.
