Hi I recently bought a second emp about 2 weeks after I bought my first one. Upon their initial meeting, there was a bit of a scuffle but afterwards the two were resting together in the same burrow. I noticed later on that the new emp can't open his/ her right claw but can move the arm. I've been monitoring my emps claw and it's still been the same for the last 3 days. Is this something I should be worried about?
