L klugi supposedly either holds or once held the weight record for all theraphosids. Sounds like yours might be a little overweight. Mine is around 5-+ but has been a picky eater as of late. Hopefully she/it will come out of this phase soon! Good luck with yours.
Mine is a sho-nuff beeyotch! She will throw a threat with the least of provocations. However, it's all bluff- cuz you can scoop her right up thereafter and she's very calm. She would certainly nail someone if they were stupid enough to touch her on the front feet/business end!!
