Mini Hearth (Dark Blue 1623) Fortress the Atrium is larger (available

the Atrium is larger (available nest space) than the Casita and would be in between the Casita and Nucleus III in terms of nest space

This is a very similar design to our popular Fortress formicarium

We found our Camponotus chromaiodes queens raised in these setups had quicker time from eggs to workers then test tube setups
