Hi, im new to the tarantula hobby and i need help, i have a 10" x 6" x 6" enclosure and i would love to put something in it but i'm not sure what. I've heard of the rule where the leg length and width of the enclosure, but i've heard different numbers and different ratios, can someone give me some cheap, uncommon species that would be good for that enclosure? I would prefer something closer to adulthood, but i know that adults are expensive. Thoughts? Thanks in advance!
