I am going to tag this page on my "important" section for reference on my own growing lasius colony! Amazing work here!
I'd suggest that if you eventually choose to downsize again, save some of the brood (and a few workers, of course) to give away, either to parasitic queens, or to other ant keepers! Very useful for a lot of things.
Currently raising:
Manica invidia (1 queen + ~30 workers)
Manica invidia (3 colonies, 3 queens plus brood)
Lasius niger (single queen + ~200+ workers)
Lasius americanus (3 colonies, ~5 workers p/colony)
Tetramorium immigrans (1 queen + ~1200 workers)
Tetramorium immigrans (3 colonies, 3 queens)
