I made this formicarium years ago, before I knew that Hydrostone expanded, so it's got tons of micro cracks all over it. It's basically three little tiny founding formicariums put together. They each have a little water tank for hydration. If anyone in the area wants this, they can come get it. I'm moving, so I'm trying to get rid of things. Even though I don't want this, I'd hate to just throw it away.
