THis is what I see on the notatus here, and the males in some populations
have heavy spotting on the back and fins. Females have the spots too, but
they are just dark brown, where the males are chocolate brown to black.
Sajjads comment is also a good , as the difference in full grown adults fins
can be seen even without putting them in a clear container, its that
different. I still have yet to find out any hard fast rules for telling the
two apart,
