We have a mystery fish this year. We are in NYS, an hour and change north of the city. We have a garden pond fed by an intermittent stream/roadside ditch. Usually we have crayfish, bullfrog tadpoles, a few wee smallmouth bass and some sunnies, as well as the pond fish.

This year we had a stranger. It's about four inches long, grey with a sort of lateral stripey look, and a very blunt head with sort of barnacle-looking bumps on its forehead. Very distinctive. We are not sure whether to put him back in the pond or quarantine him. I took a full body shot OK but the closeup didn't come out. If I can figure out how to post the photo I will.
