I handle some of them on occasion. Of the ones I put pictures of the first four are handleable and the last two aren't. The thing about handling is that it doesn't really enrich the spider in any way and it could be dangerous for the spider if they suffer a fall. That being said there are situations where a spider might do something unpredictable like run up your arm. In those instances I feel it is important to be accustomed to handling so you can remain calm and not fling your spider across the room. Handling is also a great way to warm people up to them.
The cyanapubescans is very skittish and the ornata is shy and defensive with a painful bite, that is why I do not intentionally handle those T's.
Mostly I think of them as like fish a viewing kind of baby rather than I hands on one. I've never been that great at distinguishing though...sometimes I will lightly pet my
Goldfish, or let them nibble my fingers.
The T's eat live insects. Mine eat a diet of crickets and lobster roaches with the occasional meal-worm. They only need to eat once a week or so.
