How long before he settled down? Raphael is still pacing the enclosure, digging at the corners, etc.When I first separated my Russians (because of dominance and aggression) the aggressor (raphael in your case) searched all over for the missing tortoises which were now in a separate enclosure. I don't think he was affectionately looking for them, rather pacing his territory to confirm the intruders were gone. Within no time, he settled down and enjoyed solo living.
Thank you for your input.
