I've got a couple of very small colonies that will soon be to the point where I want to move them out of their test tube setup into something kind of cool, i.e. build my own formicarium. Can we all try and contribute to what items/materials that might be useful? Both the containers to use, and the substrate or what not to fill them with?
For example, I know you can use plaster of paris. Pros I believe - cheap. Cons I believe - heavy. Not transparent of course.
I've also read people mention hydrostone, but have no idea how it works.
Links to clear containers that fit inside other clear containers with a little space in between the walls so ants can nest in dirt there and be viable would be helpful.
Anything and everything that might help build a sweet formicarium!
Thanks!
