I know this might stir up a lot of controversy, but I never see my tarantulas get overly fat, I feed everyday, with lats that are the same length as the abdomen or a bit bigger, and they never get too fat, they just stop eating for a few days then molt. Now I've seen pics of tarantulas getting fed less and getting a lot fatter. I have 7 Ts and they never get too fat. Do they adjust their metabolism depending on how much they are fed that's why if it is used to getting fed more often, it will still be the same with another T getting fed less?
