So, I have 5 German Blues. I'm not sure whether they're male or female. I've read all of the signs for them being each sex, but all of my rams have traits on each side. One with a high spiked dorsal, but it also has black on its pelvic fin, and small amounts of blue on the outside of its black spot. I have one with no blue in the black spot, but black on the pelvic fins. Are some traits more noteworthy than others?
