You might be wondering how the hell we keep hundreds and sometimes over a thousand colonies of ants at a time. The answer is these test tube outworlds! They are perfect for 16 and 20mm test tubes, and allow easy feeding and containment for the vast majority of ant species!
The outworlds are 8 inches in length and 1 1/4 inches in width and height.
This product is from Canada Ant Colony. The full catalogue, including all variants, can be found at https://canada-ant-colony.com
