Blue tail on Redfish?

[Duck Butter]

pretty obvious the fish with blue tails are feeding, because they got hooked right

and what about the other 95 + % of the reds that get caught (while feeding presumably) that do not have blue tails?

I am just stirring the pot, don't know but I do know that everytime my grandpa would take me bream fishing and caught a bull bream and it peed he said they were bedding. Next time you catch a bull bream squeeze him and see if he pees. I will bet $100 saltycash that every single one of them you squeeze no matter what time of the year will pee, so that is debunked. However, if you spit on your cricket after you put him on the hook, there is a 150% better chance to catch a bream and that is the gospel truth
