The absalute best method for taming these creatures it to drop them in a small box, (you can use a ptera for that). Once it's in the box all you have to do is get a heap of mejoberries, then to tame simply trap it in the corner of the box. The reason for this is that it's always in "bug mode" (the mode were it gets scared or something and it's taming percentage drops). But this way it's taming percentage does not drop at all for some reason. I have tamed multiple max level pego's with this method. Do not listen to what people say about having it in a large space. Go for small and trap it in the corner, as simple as that.
literally bought console ark after playing mobile ark for ages, this little sh it came and robbed me of my tranq arrows, then, had the audacity to come and tame itself on me after taking my 20 mejoberries, didn’t want this pet but I took it home, died 20 seconds later to a bird that picked it up and ate it, still don’t know why or how but I also don’t care
