I have never dissected young floridae, so I cannot say for sure. All of the
ones I have raised have the spot in the dorsal fin to start out with. The
males will start showing more blue spots on the side and some red tints in
the fins. Then the dorsal spot dissappears when they are fully mature and
colored up. The strain I have the females have a lot of blue spangles on
them as well, but no red. I would guess by the gradual but predictable color
change they are not all females turning into males, just that the females
retain more juvenile colors. I guess typical with fish and birds often.
