Arboreal Enclosure size?

Sorry for the newbie type question. (though when it comes to arboreals I'm a novice in essence only owning terrestrial)

But I got a 11" high 7" wide hexagonal tank, I wanted to know if it is big enough to house an arboreal. I think it may fit most avics. and psalmopoeus but maybe too small for pokies. What do the experienced arboreal keepers have to say?

Thanks.

I would think it's probably okay for a smaller avic...definitely a minatrix 'cause those guys are tiny and probably for most others as well, though I would get something bigger for a braunshauseni since they are obviously a bit bigger. I don't have any psalmos so I wouldn't really know what would be best for them. And a pokie (or at least an adult) I would say get something taller 'cause they're so long and leggy. Hope that helps.
