Beaver Brook

I went fly fishing Saturday and Sunday, and was actually successful for the first time!!! Saturday, I went to an open lake to practice, and caught a couple small bluegills. Sunday, I went to 2 different streams, the first one had wild brook trout. I had multiple bites, but only brought one to hand. When I first got there, I had a nice 10 inch fish on the first cast, with amazing colors too, but I wasn't ready for a bite that quick. The second stream had some more bluegill, as well as creek chub and some type of roach or shiner. Redfin shiner maybe? No clue, but feel free to let me know what that 2nd fish is.
