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.
Manica invidia (1 queen, ~200 workers)
Manica invidia (1 colonies, 1 queens plus 3 workers)
Lasius niger (single queen, ~200 workers - naturalistic, predatory set-up)
Lasius americanus (1 colony, ~10 workers)
Tetramorium immigrans (3 colonies, 3 queens, ~ five workers each | 1 colony, 1 queen, ~1200 workers)
Formica aserva (aserva queen, ~15 ​Formica neorufibarbis workers)
