That totally happens. Usually its a bluegill and they get right up in your business and bite your moles and nipples, it sucks! But is kinda funny. When I was a kid we used to try and spear em before they could attack us, we always lost.

kid when i was younger got his nipple bit off. it is normally blue gill/perch
