I found a picture frame which I thought could be used to make a formicarium. I don't have Pop, gypsum, hydro stone, pumice and other related stuff.
I was thinking cork, soil and sponge? Here's a picture of the frame:
I need to know whether it can be used to make a formicarium. Size won't be a matter since my ants are very small, the queen is only around 4mm and the workers are 1 or 2mm.
I also want to know, if it needs to be hydrated in the nest too, or just connecting the nest to a test tube with water will work.
If you need any more detail of the frame, please ask, thanks!
