I basically agree with Bruce's comments. Although for Fish #2 I would not stock this into an all male pond. Too much room (even 5%) for doubt in my opinion. This fish is around 10" long and should by now have at least a couple dark nape scales. It should also have at least a little darkness in the gular area. I have sometimes seen some large female bgill (9"+) with fairly large gill flaps similar to that the No 2 fish. I would want to see some males from this pond before I put any money on if this fish is male or female. I like to be 100% when stocking all male bgill. That why I have no BG offspring so far in my all male BG pond.
The last (No.3) fish's coloration looks to me a little more like a female than fish No 2. However the gill flap is at an angle and not in a good view due to the gill being partially open.
