I am selling a M. barbarus colony, queen + 500 ants with formicarium included.
I will wait for interested forum members before I sell them to an ant store, as I have no room to keep them.
The formicarium is a modular substrate type and consists of 4 identical modules that can interconnect in different fashions.
I live in Croatia, Europe, and will ship to any countries where import of ants is legal.
Contact me for any questions you might have.
