P18 Spotted at Hendrie Valley Marsh Sanctuary
Not positive on the ID here. Big school of a few hundred. I managed to capture 4 diffierent individuals, but not sure if Spottail or Spotfin Shiners. Spottails aren't in the watershed reports for this stretch.
Finally got one that could be positively ID
