In the same boat here. My 800 gram female pastel has been off feed for a month now and has never missed a meal since I got her as a hatchling. Now today my 900 gram spider decided he would join in and he has never missed a meal. Could it be the dreaded 1000 gram wall I have read about? Of course mine or not at 1000 yet but i suppose its close enough
