Like most island boas, they are quite nippy and tend to not grow out of it. As always, there is exceptions, but most I've seen are like this. Also, like most island boas, they're not as easy to breed to as a common boa or ball python might be. Humidity and temp fluxes are a must to inspire breeding. Vin Russo's new book would be a great source of professional advice on the specifics of breeding and/or keeping any insular/island/or locale specific boa.
