So I saw a fish in the ghost shrimp tank at my LFS and when I asked about it they didn't know what it was. It came for free with tbe feeder guppies. Sooooo I took it home lol. No idea what it is though. Any thoughts. I'd assume it's some sorta goby
Looks like some sort of darter to me. Perhaps Percina copelandi. I'm far from an expert on these fish, though. The people in the Cold Water, Temperate and N.A. Native Fish section might be able to help get a more accurate ID.
