In my experience it depends on the BP. I've had it where the male I used to work with came out on his own almost every time but I've also had it where my baby male doesn't want to come over. I think it's partly a personality thing and a consistent thing. Like if I stood at my baby's tank while I had it open I feel like he'd come over eventually but he has to get used to that and get comfortable. For a shyer BP that may never happen but who knows if you take the time and wait them out their curiosity might get the better of them.
