I have fed in separate tubs and noticed similar reactions with my ball pythons. I feed f/t so I kind of think the smell of thawing rodents tends to get them excited. I found that ball pythons can be fairly easily conditioned to feeding in a separate location. I would actually encourage people who use aquariums to feed in a separate tub/tank. If you use a rack system it doesn't make too much difference to them in my opinion.
