I found some pretty sweet containers for formicariums. I saw them at target and it was love at first sight. I went crazy and bought all eight that they had. They are clear and and the lids are just a thin plastic. So you can add some sort of vent or opening fairly easily. They come in a few different sizes, so check them all out. I wish they didn't have the gaskets, but that's not a big deal.
