Drew, you should try placing blue death feigning beetles(Asbolus verrocosus) with that Hadrurus arizonensis. They cohabitate and the beetles eat the leftover dead food and scorpion excrement. The scorpions don't seem to eat them, and from research, they seem beneficial. The beetles are pretty cute and play dead if you handle them, hence their common name- blue death feigning beetles
Proverbs 6:6-8 New International Version (NIV)
6 Go to the ant, you sluggard;
consider its ways and be wise!
7 It has no commander,
no overseer or ruler,
8 yet it stores its provisions in summer
and gathers its food at harvest.
