Actually mine don't do any of the stuff Jane just said. But they are WC so that could be the difference. But what I mean when I say they have personality is that, well, they have personality. They each have their own. For instance, my female, Mary, is a fat and lazy one, while my male Peter Van Holp ( weird name I know ) is very active and thin. And then there's Katrinka whose fat, happy, active, stubborn, and patient.
Anyway if you want a
salamander and not a newt, and you want one that isn't super common in captivity than I would say maybe fire salamanders.

They are very pretty colors and such. They aren't that hard to keep as far as I know, but aren't super easy either.
That's just my suggestion.
I agree with Jan, what do you mean by 'communal'? Because mixing species is a pretty bad idea.
Oh, and another thing about
T. granulosa is that they are brightly colored. they have yellow or orange bellies. And they are also EXTREMELY toxic. There poison is tetrodoxin, some of the most deadly poison known to science.
