Best formicarium for Crematogaster?

[Martialis]

I recently caught a Crematogster queen, and am looking at AntsCanada for a habitat for her. What is the best formicarium/setup sold by them for this genus? Thanks!

I would say Formica Hybrid nest, or if you want to create your own, make it kind of wide and kind of small. From the various nests I've seen in the wild, they don't tunnel so much, (the species that actually live in the dirt) so not too tight spaces but not too wide either.

I have 3 or 4 queens of this genus, so good luck!

What is the best overall setup for this genus of ants.
I.e: outworld size and terrain, tubing etc,
Pictures would be helpful.
