Awesome to hear about your Spider!
I have a male Spider that is almost exactly the same. Eats like a champ, never strikes, hisses or balls up and he loves to explore. He wobbles a bit but it makes it seem like he's got more personality.
He's even lately been coiling around my arm and falling asleep!
Congrats on your Spider (they're hands down my favorite morph) and good to hear you're having success!
