Just ordered my first 2 T's, which are a Mexican Red Knee and a P. Irminia. Glad to finally start my collection, I have experience with a few T's such as the B. Smithi, OBT, and Cobalt blue, ive heard they Mexican Red Knee's were pretty docile, so theres no concern for them, but if there is any information you can share from experience with the P. Irminia's it would be helpful
