Ok, I went back to my original photo and blew it up. It gets grainy fast, but it looks like to me we might be looking at the second gill arch instead of the first. I can see only one other gill arch behind.
Also look at the second arch on Lovnlivin's picture. Look at how numerous the protrusions are. They are also numerous on my picture. Lots more than on sprkplug's RES or even the RES/BG hybrid.
Now I'm leaning towards sprkplug and Esshup being correct with their observation of it being a BCP.
Guess if I had to loose a fish it was the right one to loose. Sometimes being lucky works out.
I'll be interested if others come up with different observations than what I have expressed.
