Pics of male vs female?

[fishlvr]

Does anyone have any pics of the differences in anal fin size/thickness? I've heard that males have thicker anal fins, but I just need to know how much thicker.

Yeah seeing this is actually pretty cool too.

fishlvr - A male's anal fin is MUCH thicker than a female. I find that the female's anal fin is almost see-through for 1/2 of it, while a males is almost fully colored in.
