My Connecticut forest terrarium had nearly all of its inhabitants die off due to the first winter chills, and I decided to make it into a (nearly) all ant terrarium. It has a screen lid that a C. chromaiodes nanitic can barely squeeze through, so I might need to start making barriers. All of my current colonies are very hardy and active, thus making all of them great choices for my terrarium. I am having some difficulty choosing between my colonies, though. Any suggestions?
Here is the list:
C. chromaiodes (wild caught colony, 30-50 workers)
C. pennsylvanicus (wild caught colony, 30-35 workers)
Formica sp. (wild caught colony, 10-15 workers)
For Camponotus, I'm thinking about cutting a rotten log into pieces and carving a nest into a flat piece, with the nest being pressed up against the glass. If I do, should i use store-bought firewood/fresh wood or rotting wood from my backyard (natural Camponotus nest fragments, I still have the C. chromaiodes nest chamber).
Also, would it be safe to include the following animals?:
