Keep them very humid! Especially with avicularia and especially when they're young, humidity is VERY important to keep them hydrated. What's your setup like for the little guy?
I just moved him into a small-ish plastic container with small holes in it, and a piece of wood to take up some room in it... he was in a small vile that he came in from the store.
