I was just at the pond looking things over and spotted a fish near the surface that looked odd. Upon closer look, the tag told me it was one of the Smallmouth I stocked about 8 weeks ago. It was very healthy at the time. Now, he has turned black on the last third or so. What caused this? Has anyone seen it before? No fungus or anything seemed wrong other than it's black and it did not appear bothered by me and I got very close to take the picture.
