Hello. I've had arachnids for a long time now, but I finally got around to getting my female emperor gravid several months ago. Recently she has become visibly gravid, and now she seems as if she's going to burst at any given moment. However, her behavior has changed radically. She's fasting, which I hear is typical. BUT.. for some odd reason during the night she props her self up against the glass and she also does laps around the tank. What do these behaviors mean? Is something wrong?
