What else is in the pond? Creek chub need moving water to spawn, so in a pond they cannot reproduce.
Well I stocked with fishing minnows from a bait supplier and put in about 36 dozen emerald shiners, Just recently about three weeks maybe four weeks ago we put in 5 dozen fathead minnows.
These are all I stocked or placed into my pond. I am guessing that this guy was in the original minnow stock back in November because of the size of him. I do have a water fall feature on the pond with river rock deep into the pond under the falls.
Water fall Cheers Don.
P.S. we let him go back into the pond.
