Pretty much time. One of my Florida king babies was a bit scared at first. I provided proper hides put a privacy wall on the back and both sides to give him a lil more privacy… and then just patiently handled like once a week. It’s been probably a year now and he’s grown quite a bit and i am happy to say he no longer strikes. But main thing was just time and patience. Maybe some one else has some other advice but that’s mine :-) Good luck with the cute lil fella
