Gruni, it is very difficult to give you a precise behaviours to look out for as each animal dispays different behaviours when they are comfortable in their environments just as they do when they are stressed. Antaresia can stop eating when they are stressed so it easier to go by consistent feeding in their new environment. For an Antaresia I would suggest consistant feeds are between 5-10 for a yearling (IMO). If he stops eating then stop handling.
I've had a childreni that cruised around, didn't bother using his hides day or night or worry about hands going in and out of the enclosure to change water or clean and was quite inqusitive but he didn't eat for weeks. In a click-clack next to him was another that stayed in his hide, only came out at night, was defensive if you put a hand in his click-clack, but was a voracious feeder. Neither were being handled and both were settling in.
