I have a couple smaller colonies of tetramorium immigrans, I caught the queens earlier this year, during this nuptial flight season. Now however, they have a lot more ants, I currently have them nested in AntsCanada ant portals with their founding testtube connected. They have more than 50 ants, but as tetramorium immigrans is a smaller species they still haven't filled up their testube. At what point should I move them into a actual formicarium. Should i move them now? should I move them once they get to a specific number of ants EX: 100? should I wait till they use up the majority of their space in their test tube. Below are pictures of my two colonies.
