Can anyone ID these minnows? I believe the big one is the common shiner.No idea on the second smaller one.

Also wondering if these would be good or bad to put in my pond.

1 acre, max depth of 16', 500 perch, 25 walleye, 25 hybrid bluegill, 1 smallmouth bass.

Was able to train these wild perch to feed off pellets!
