The male is trying to "impress" the female. They are flirting. Although not as colorful as te female...they do color up nicely. He's still a juvenile. I'm terrible on the size thing. Aikido Guy gave me the female...and has seen the male. Maybe he will venture a guess. Mine is 10".
When i got the female ready for the haul to Mos place I physically measured the fish with a ruler. She was exactly 7" from head to tail. That male is a little less that twice her length, but is much taller and thicker bodied. 12" wouldnt be stretching the truth on that male.
