I'm just starting, gathered some info about starter t's. So I have a few species in mind. Would buying online compared to at a live expo, or from an individual seller be a huge difference? I'd really like to know the temperament? I'm thinking a juvenile probably to start with. I don't think a sling would be easier. Was thinking Arizona blonde, smithi, or euthulus sp red ( think that's the dwarf Chilean) trying to keep track. Just size and species feedback would help.
