BP's are ambush predators so if your BP is hiding then hes being a BP. If he (or she) starts doing the opposite and constantly moving around and not settling then you know he is unhappy and needs a change. But seeing as how he is hiding then it sounds like you have a happy bp so don't worry. Also In my experiance its not that uncommon for young bp's to be kinda aggressive and that in time that will pass and you bp will settle in.

So congrats on getting your 1st BP
