#1 has a lot of GSF traits but ironically, looks like Tilapia lips :-))
#2 is a male CNBG in fairly poor body condition.
#3 also has a lot of GSF traits but I don't believe it's "only" GSF.
#4 same as #3 but large tab would indicate a male.
#5 is a Female CNBG in much better shape than #2 specimen.

I think 1, 3 & 4 are all the same hybrid, GSF X "what"??
I personally don't see RES traits in any but that's my view..
