Although there is a picture of the BP and the Boa and the anaconda together, do we know for certain that he houses them together? If he has them out together playing with them maybe that is where the pic came from.
I take more than one of my BPs out at once occasionally, and they do play(spar?) and wind around each other, but they always go back into their individual containers.
Just wondering bc after reading the thread it didn't actually say that he housed them together. The first picture looked like a lovely set up to me, with a large clean water pan. If the only issue is him keeping them together, well I'd have to say I would rather see that than non-heated filthy cramped cages out of wire. Might not be perfect, but the snakes look healthy.
Me personally I would never let a small child sit with a snake that large on them, I would consider that to be hideous practice for an experianced keeper, but that is only MY opinion. I let kids pet mine, but rarely ever hold them and NEVER hold them by themselves.(My larger BPs, some kids do get to hold my smaller ones if I know the kid and trust them)
