Well the guy who posted his comparisons in that thread is on the right track, Dominant males will show at sizes as early as 3" same with dominant females but wont be ready to spawn untill 3.5-4" That thread doesnt mean its 100% accurate as far as the female goes, but if you take another look youll see the male has tiny pearling along his back and dorsal whereas the female does not. the females will definitely take a while before showing nice blues, more so yellows than anything. the dominant males will have a better shine and color than the rest of the group immediately. if you have extra room pull out the dominant male in a week and put in different tank preferably divided, then when your have one you think is female or the next dominant male place them on other side of the divider from the first male and within a couple weeks they will both be eating like hogs and coloring up like crazy also allowing the others in the group to get some more size on toe better sex them.
Thats a good idea....i will make some room and split the tank and see what happens...i will see what kind of space i can find tomorrow. Thanks for the valuable info...
