I have a pair of ocellaris clowns, a black female and regular orange male. I've had the female for three years and she was a little more mellow before I added the male a few weeks ago. Still peaceful but just there's a little more boldness to her personality. She's never bitten me before but if I get too close she tries to bat me with her tail. Btw, they became a pair without a hitch... hardly any aggression. However, she wouldn't allow him to spend the night in the brain coral she hosts until after the third day... she feared commitment I guess.
