Went down to Rockmill lake in Lancaster again today. I caught a bluegill and another fish that I am not too sure on what it is. Can one of you help out? It was sunny and warm. My girlfriend and I only caught 2 fish. Well I caught 2 fish. She lost a bluegill at the bank. She isn't having very good luck the last couple of times out. The water was lower today than it was last weekend. What is this fish? I snagged him with a rooster tail in the dorsal fin.
