This is very true about the versicolor. Good humidity is important, but hard to obtain in a dry climate like AZ or even here in CO. But we've been lucky. Wife is actually looking forward to having ours shoot poop on her. (I think she's a little insane)
The GBB will "investigate" anything that enters their tank. Ours will run in the direction of the needle nose pliers when trying to get cricket balls out. It's a bit freaky because she is fast. She shoots hairs which are irritating. But the mass amounts of web-work is nice.
The A. Metallica is also another T that needs height and good humidity. They are also skittish and fast in general.
