Yes they will, how much bigger was the prey than the BP? He might be fine, just a little stuffed depending on how big it was. You might wait a while for him to digest a big meal like that. If it's TOO big, they'll possibly regurge.
well, I guess stretched out it was about ass big around as he is, but thats just when stretched. For all I know it may have been about time to move him up in size anyway, it just looked really big comparitively. It also took him a couple strikes to kill it, which he hasn't had to do before.
