I've seen people claim that they're the largest of the 'dwarf' species, as they can reach lengths of up to 15ft. But I've also seen pictures of much smaller specimenes, and comments from other people swearing that such a size is exaggerated, and that a male won't get more than 7 or 8ft. So, which is true? And furthermore, what are they like? I'd love a male, but not if it'll get 13ft and be flighty or defensive.

I apologise for posting this question, when I know full well that it (and similar versions) have been posted before, but I've read so much conflicting information and would really appreciate hearing for myself what experienced people - who know what they're talking about - have to say about them.
