I would prefer a boa constrictor over anything else basically. But yellow anaconda and bci require almost the same cage size because they reach almost the same size as adults, the one who was better fed and had better husbandary will be the bigger one at the end. I just finished the adult cage for my 17 months old bci, size in feet: 7,20 long, 2,60 deep, 4,60 high. I might post photos later. Also meal sizes are the same, my male bci just ate his live large rat yesterday (300g). When it comes to poop, bci,s poop don,t smell that bad, very normal and once every 2 weeks on average. I read that yellow anaconda,s poop smells horrible and that they pee and poop too often and that they like to do it in water.
