Update: After about 2 days they started getting along more or less fine. The big guy will occasionally charge the little guy just to show who's boss, I guess, but there's no contact. The little guy is eating like a pig now and a lot bolder.
That's the good news. The bad news .... I'm pretty sure he's another virgatus not a doliatus. Argh! What is with this whole "no doliatus's in Canada since at least August 2006" thing???
Bummer ... I guess I will keep hoping for one someday.
