I have three BP's.
They are the nastiest things I own.
Cleaning their tank is a huge pain in the rear. I use a very long gravel vac tube and the still push it and bump it all over.
Frankly, since they got so big, they kinda scare me
That said, I still love mine and would take yours in a heartbeat if you lived close.
Point is, I don't think the personality is going to change...
On the plus side, the bites don't really hurt...unless they catch your pinkie finger at the right angle
BTW, they get pretty damn big...when mine get big enough to fit my thumb in their mouths, I'm gonna hire someone else to clean the tank...
