Anthriss is the last of the Challenge Tames that I've yet to tame, so I unfortunately cannot speak from experience. And I doubt I ever will, for two reasons.
The first is that Anthriss spawns in a very easy location to get to. As a result, any hunter happening to work on dailies, rather than Rare Hunters, will be able to see him, and probably kill him rather than tame him, as he is a little bit difficult.
