Advertisement A few weeks ago, we picked up an Emp to bring to the family... We figured he (or she) would be a nice, docile pet to enjoy observing. For one, s/he is a spawn of Satan. This sounds like a joke. The first couple days s/he acted like a normal Emp, hiding out, doing his/her scorpion thing. (Getting used to a new environment) Then s/he became excessively aggressive. I went to change out the dead plant life and s/he stung one of the bark pieces I placed in the tank 6 times. S/he likes ripping the heads off crickets before eating them. It's awesome...and frightening to watch...I've never seen a scorpion do this. S/he also now hangs out on top of the hidey hole, and hardly tried to hide at all. Aaannnd finally, s/he has decided s/he wants to climb EVERYTHING. Tries for hours to climb up the corners, the walls...will sit on his/her tail for hours. At the pet shop s/he was very mellow, but that's probably because of how cold it was... I keep a good amount of moist substrate in the tank, along with somewhere to hide, a water dish, and I check humidity and temperatures daily on all my tanks...could I just have picked up an odd scorpion?
