My first boa was a Hog Island, shes struck at me before, but other than that shes been really easy for me to take care of (she never refuses meals, seems to be okay with handling every couple of days).. I've heard of some being very nippy though, so I would keep that in mind.. I believe they get around 6 feet fully grown, maybe a little more/less.. depending on the sex of the snake and how much its fed.
