I got a male and a female emperor in a 100x40x40 (cm) tank. I got a stone hide at the colder side of the tank and a piece of bark in the middle. On the warm side of the tank i got a flat stone and a fake plant. The substrate i use is repti-bark. In tried potting soil in the beginning (when the scorps werent in the tank yet), but that started growing molt very fast. So i changed it to repti-bark. I got a UTH under the tank and 2 60W spots. Its about 80F - 85F in the tank.I mist the tank at least twice a day, cause its rather dry in my room. I throw in about 5-6 crickets in every feeding. I will throw in new ones as soon as the others have been eated or just died. Well thats about it i guess. And they are great pets, shame that they are nocturnal though, dont see them quite as often as i would like to seen them.
