i disagree. if you are going to get any of the avicularia species, make sure they are over an inch in size. when they are small they are so delicate and personally i've never been able to keep one alive. but when i order them over an inch... no problem! (they are higher humidity as well)

a GBB is a great first T... very colourful and out much of the time. that's what i started with. OBT is great but fast and something like an n. chromatus is great cause you see it all the time.

it's almost better to do a search, find a few Ts you really like and then say, "are these good beginners" cause so many are good for a beginner. Ts are not all that hard to own and raise. little care and hours of enjoyment!
