True, but I doubt youd find that with most snakes
Seriously, the idea that brb's are nippy is kinda blown out of proportion. Yes, babies bite, but so do baby ball pythons and corn snakes. Ive been keeping brazilians for years and have friends that have as well. Honestly, Ive found most people who say brazilians are "known for being nippy" either havent kept them personally or have been working with imported animals.
Id still like to know how often he is being fed. Also, what kind of gloves are you using? What kind of hides do you have set up and what are your temps at?
