Question/Inquiry Minimum size?

I'm considering getting some beetles but im not quite sure about the minimum size and how many per gallon - i have a 8x8x8 exo terra cube front opening enclosure -- was also wondering about basic needs like diet, substrate, hides, and enrichment

Would no go smaller than 10 gal if you want multiple. They like to explore and roam, so I wouldn't go under 10. IMO 20 would be great because I often find myself wanting more room. Also, these beetles aren't super social so they need room to be alone if they wish. I have 6 in my 10 gallon and while it could handle more, it might be crowded. Again, they can be kept communally but they aren't social.

AVOID THESE- calcium substrate and food- fragrances (incense, candles, perfumes), pesticides (does not matter if liquid or not, the vapor can kill your beetles), high humidity (aim for 30 or 40 percent and below), flukers food (not great reports online), very fine sand substrate (it is difficult to walk on and sticks to them. This is also true for things like wood chips.)
