I've never owned a Hogg, but from what I've seen they're temperament is along the lines of a Colombian; most hatchlings are unpredictable while a few are just plain nasty, but with handling they're almost guaranteed to be sweet, wonderful adults. But it is best to find a hatchling that is well behaved. Though most over-the-top defensive hatchlings will calm down with proper care, your best bet is to find one that seems at least somewhat docile.

Yes, care is very similar to that of other Bci with caging and feeding adjustments based on size.
