I'm wondering about your question asking if Arrie will relax because he is apparently stiff when being handled. None of my corns, regardless of age are stiff when taken out of their containers. Typically, the young ones will attempt to flee so I let them slither through my fingers until they finally calm down and decide nothing is going to harm them. The older ones are calm anyway and are relaxed and easily handled. Arrie seems to be doing well, just keep handling him and he should be fine.
