How in the world do you know this? Do the BPs go to the swamps to hunt, then return to the ever-necessary grassland surrounded termite mound when they are full? The fact is, these animals are extremely adaptable in the wild and in captivity.

Think about BCI and the incredibly diverse conditions they are found, from rainforest to desert, and everything in between. These things are only fragile in a 20 long.
