These test tube ports make it very easy to expand the capabilities of test tubes within the ant-keeping hobby.  For example, the two-port option is perfect for test tube transfers or the initial expansion a new colony needs without connecting a giant nest; giving too much space is often the number one mistake we make when starting. 


The port is designed to have as little space within its tunnels to avoid ants using it as a chamber, encouraging them to keep it clean, so it is only used for travelling traffic.


The port aligns perfectly with the back hole opening of our out-worlds; you can skip the hose between them by gluing it directly on the back with a tiny bit of fish tank-safe silicone, this allows you to use the entire inside diameter.


We use this test tube port on our "Test Tube Array Formicarium," but we also have the part itself available for the DIYer; they fit all of our test tubes to perfection, it is expandable, and your imagination is the limit.  


Includes white test tube port with rear stand, silicone fittings for each tube, an entrance plug and 5 cm of vinyl tubing.
