So you can't speak on whether the statement you made and are defending vehemently is true or false on personal experience or scientific data..From terrestrial tarantulas i have:Aphonopelma seemanni,Acanthoscurria Chacoana,Acanthoscurria geniculata,Brachypelma vagans and Grammostola pulchripes.Bu overall i am more into reptiles than inverts.
