I went into a local pet & feed store the other day, and they had a tank labeled "Emperor Scoprions". They had this one they were trying to get rid of because they said he was "really mean" and was attacking all of the other Emps. It was a communal tank, but not overcrowded, only about 3-4 Emps for a 40 gallon or so tank, and it seemed to be perfect conditions. I asked to see it, and noticed that it was in fact not a P. imp at all but instead a Heterometrus of some sort! I didn't say anything though because they offered to give me a discounted price to buy it since they said it was hostile, so I agreed and took it home. Just thought I'd share this little story with you, doesn't really have a point but I just thought it was funny.
