I would say that the bp will be fine, it is just being a stubborn little thing.
I have a cork tunnel log in my tank and its a decent size, but I've learned once my bp gets in there, there is no way I can get him out. But I know for sure he can come out on his own. IT make seem like he is stuck but hes most likely not, he may just love the security of such a tightly enclosed space.... Just like my bp haha. Lets just say i regret putting that log in there but I let him have it because I know it makes him feel secure.
