My 3 month old bp appears to have been trying to escape for the past few days. He hides all day, but around 9 pm, he gets pretty active - typically climbing up the branches in his tank and hanging out near the top. Is this normal bp behavior, or a sign of some sort of discontent on his part? I was having some habitat issues when I first brought him home but I'm fairly sure they're all corrected now (and for the record, the top of the tank is lockable and secure enough that even I have to put in some not insignificant effort to open it, so I don't think he actually will be able to escape).
