Great tarantulas. The one on top, however, is not a "Mexican Red Knee". It is a Brachypelma emelia or "Mexican Redleg". A great species and typically pretty docile. They get to a decent size and are stunning (in my opinon) right after they molt. I've got one myself. Mine is unfortunately a male though.
(Thanks Marcus)

Mike: the redlegs are BEAUTIFUL, and to be honest at this point I see so many Red Knees, I'd rather see the less common red leg!
Great T to watch and care for! Congrats!
