I wanted to let you know of a new product I am formulating. It all came from earlier this year. I have a tetra colony with about 30 workers, and a formica colony with nanitics. I put them in a mini hearth, because they needed an outworld, but quite frankly, the nest is too big for them, and unnecessary. The idea here, is that you'd have a test tube connected to this small outworld, so that small colonies could live in a test tube, but still have foraging space. I am going to be selling premium outworlds for small colonies and queens. They are 4x4x4, have a tight fitting lid, and are premium acrylic. I am going to have a small bottom layer of hydrostone, coated in sand, with decorations as well. I believe they are going to be sold for $15. There will also be connection ports that you can personalize, for example, you can pick the sizes and placement. The default size will be 3/8 inch OD. What do you guys think? Please let me know, any and all advice is appreciated!
