My GBB trying its hardest to be a Facehugger.
Tarantulas are pretty much blind...if that was your finger it would be throbbing now. I try to stay away from tong feeding. Tarantulas can break or damage their fangs doing so. If you have ever seen someone that has had to feed a T with one or no fangs it's not fun. At least you are using bamboo tongs. Gbbs are much funner to watch hunt. Drop the roach off to one side of the entrance and watch the show.
I tease my Davus pentaloris with a piece of grass or straw to come out and eat. Try that...make sure the grass is long though otherwise it will end up on your hand.
