Oddities?

Anyone see trout swimming on their backs?
Watching from directly downstream these 10" (inches Thomas
drifted up to the dry, hung vertical, while inspecting the fly, then
appeared to complete a reverse somersault after deciding to reject the fly.


Double dorsal? A small pro-dorsal fin over the head (and thus well forward
of the normal position) on an 8" fish (different river to the Flippers ).
The fin had 3 rays and is about 1/4" long.

Do you see a lot of deformities in fish?
