Hi everyone, after getting a lot of help here escape-proofing the formicarium, I'm trying to move my colony of Monomorium minimum into it. I've attached the test tube they're in currently to it, but the tubing connecting the two is really long, because I had to attach 3 sizes of tube end to end in order to get it down to the right size.There are 6 queens, and one of them moved in very quickly (a few hours). However, a day later, the other 5 don't seem to have any intention of leaving the test tube, as they have a massive brood pile. How should I encourage them to move out? I've attempted to attach an image of the current setup.
