I just got a colony of Brachymyrmex patagonicus with 3 nanitics, and I'm looking into a good founding formicarium for them. Even most founding formicaria are too large for them. I've been looking into the THA Atom Nest. I've seen Brachymyrmex in them before. I'm just confused about the hydration. From the pictures on their website, it seems like it's kept hydrated through a Nestmate. Do you take the Nestmate out to refill it? Do you just inject water into the Nestmate directly? Or is there some other way to hydrate it that isn't shown?
Are there any designs or types that I should look into making myself?
