Sex of this Green Terror?

[Rivers2k]

Just picked up a Gold Saum Green Terror. I think it is male bases on fins and body shape but I'm not sure. The tank shots don't show the spectacular green so I included 1 pic of the GT in the bag that shows it's color.

Please tell me what gender you think it is and how you know?

Here is a link to the album if you need more pics.

Sure looks like a fine male specimen to me. The size and shape of the fins are one way of sexing. Another clue would be the markings. What is the size of the fish ?
