Suggestions for 1st scorp

[GTPman4]

I am looking into getting my 1st scorpion within the next few weeks, but havn't been able to decide on a species. I have 2 T's, a greenbottle blue and a pink-toe( Not sure if that experience helps as far as scorpions go). I have a 10gal. tank already and was thinking about putting 2 emperors in there( not really sure if that is enough room). Do Emps. tend to fight or cannibalize when put together? Any suggestions and answers would be great!!
