Another update for those interested. There's no more aggression from our Saddleback ("Princess") to our little Ocellaris, but at the same time, there seems to be no interest. It could be he's a bit too small for her interest? Not sure... He seems interested in her, keeps swimming around her, and by her sebae, but he sleeps against the heater at night.
Have to laugh though, Hubby says I'm paired with Princess, the other day while installing the HOB Skimmer and moving some stuff for room for the powerhead the little Ocellaris bit me, and the Saddleback just came careening out of her Sebae and plastered him to the glass... It was interesting.
