Today, I noticed another sick looking fish. I will try to describe what it looked like best I can. If anyone can can indicate what could be the cause of this, it would be appreciated. I'm worried the fish are in trouble.

As I was feeding the trout, one larger one was swimming upside down / vertical right along the shoreline. It was seeking the shallowest water possible and was visibly struggling. If I had a net with me, I could've easily netted it. It was struggling to get away from me as I was following it along the shore. I would say it seemed very buoyant and could not seem to swim down. It also appeared to have a slightly bloated stomach.

The warmest the surface temperature was today was just under 14C (57F). I can't imagine that is too warm for trout, especially since the bottom would be much colder. Most fish are eating and seem normal.

Does anyone know what this could be and is it an indication of a greater problem?
