Help! I think I accidentally put a bluegill in a native tank I've set up at my school. My school owns a pond and I've been helping my science teacher set up a native aquarium. We put a minnow trap in the pond, and the other day we got what I though was a small sunfish. Later, a parent or someone who knows about fish. Came in an said "that's a bluegill." I'm still not posotive if it is, but, what do bluegills eat, how fast do they grow, etc. Can I have some basic care information. Right now it's hiding really well behind this decoration so I couldn't get a picture of it, and unfortunatly release isn't an option. What do I do?
