Advertisement So initially I planned on buying only CB spiders, but lately I've been considering getting some WC a. chalcodes and other USA T's due to the low price and also their very slow growth. My questions are: 1. What differences if any are there in WC T's? Are they eager eaters? Are they more reclusive? More defensive? Any diseases I should worry about? Thanks for your info. Also, are any of our USA T's threatened?
