He's prettylooks like you are doing well already. Cypress mulch and tub isn't too big. Maybe give him a hide? Watch the humidity. They don't like it arid.
As for the blood 'tude.... one of mine was a major B when I first got her but the calmed nicely down after handling and going to f/t. The species in general tho is just very vocal and hissy. Go more off the body language. People who I let handle mine are always put off by it at first.
There's a bunch of ppl who keep them on here, sorry I didn't have more tips. *Waits for Kara to chime in*
