I think keeping the abdomen the same size as the carapace is a little on the skinny size. Some of my Theraphosa slings have had an abdomen similar in size to the carapace right after a molt, and they weren't obese before that. However, definitely don't want to get them too fat.The smaller of my two slings was in premolt for nearly 3 weeks, and refused food for that whole period. The other, which just molted, did so only a week after its last meal. As I recall, my T. apophysis in the past didn't take very long in premolt as slings either.
