He's just a neonate right now so he will be nippy. And I have brb's being nippy to a point in general. I dont think his skin is really any more sensitive since it is covered in scales. Amphibians are very sensitive to outside toxins and handling because of their very sensitive skin, but with the reptiles the scales of the BRB are about the some of most RTB's and other tropical species. Almost all the species we keep are tropical.
