Hi! I've decided to start my own Formicarium and was wondering what I should put in it. I thought it would be a fairly common question, but when I did a search for dirt and soil I couldn't find anything on the first page of results so at th risk of annoying the ant community I thought I'd ask; What's better, sand or soil?
I've got backyard soil in my formicarium right now and I ground up some chalk rocks I found and put it in to lighten the soil so I can see my ants easier. But when I looked on the forums in a post about a queen not digging someone mentioned that trying sand might help. Does sand make it easier for them to dig or is it just easier to see the ants when they're in sand?
