I'm afraid for my aurantis it's the female that's the big bad boss. My male is quite a bit smaller, so much he could look like the female due to his shorter fins with the size difference. But if ornatipinnis are anything like aurantis, my pair are together 24/7, rubbing and nudging, you know you've never had a pair the day you finally have oneyeah but youve been keeping multiple longer!-) is there a size difference in your suspected pair shane?
