Kevin suspected it was another Oriental Weatherfish, similar to the one that Walt Staab photographed last week.
I checked with Bob Schmidt, a leading weatherfish expert, and he confirmed the I.D.
Great shots, but not good news. It's an invasive species.
I notified the state. (Thanks, Kevin and Bob!)
Last week's post explaining all about weatherfish -- with Walt's photo of an American Bittern -- is here.
