I am betting for every RRFHM there are a bunch of wild colored ones in that same BOW. Even in ponds without fish predation, RRFHM will naturally over time revert back to their natural coloration through natural selection. That is cool that there are still some RRFHM still in the population though.

The dead bullhead is interesting... Was the bullhead near one of your ponds? Do you think it came from one of them or another near by BOW?
