I have one (my first one I ever got) that does eat in a separate enclosure. All my others are in a rack and they eat just fine there without any noticeable signs of aggression. However, people who say they don't know the difference when you move them, is not true. My bp knows as soon as his tummy hits the bottom of his feeding enclosure that it's "food time". He watches me in the kitchen preparing, and literally is "S"ed up the whole time just waiting for me to drop something in. None of my bps are aggressive, and depending on the bp itself it can be more stressful to remove it from it's enclosure each time to feed. I have two that I know wouldn't eat if I moved them at all.
