    The Fortress formicarium from Tar Heel Ants is designed for founding queens and small colonies.   What makes this formicarium special?  This formicarium is designed to keep ant colonies in the founding stage from storing trash in expansion parts of the nest.  This is done by positioning the founding chamber (water tower chamber) on the same level as the foraging area while keeping expansion areas above.   This design is also incorporated into our Stronghold formicarium.

    Check out this new review of the Fortress by The Ant Network:



    Decor options - the 4" height limits decor options only slightly.  The Great Tree option is available for $10 in this formicarium but please keep in mind this takes up a lot of space in the foraging area.  We find it useful in creating additonal foraging surfaces.

    Type I or Type III - This nest is for small colonies and therefore we feel either Type I (Ytong carved) or Type III (our proprietary sand-coated castings) are both good options for any species.  

    Type I vs Type III - Type I is a dryer nest than Type III all things being equal, but both are easily modified with additional nestmates for increased humidity control. Type I is a stone carved surface dyed with natural dyes while Type III has sand coated chambers.  Both have naturalistic looks.  Type III is significantly harder than Type I and aids in preventing destructive ant species from tunneling through the materials.  Again this is not a problem for many species, but if you have questions about Type I versus Type III please contact us at tarheelants@gmail.com

    Museum Glass - For $15, this is something to consider!  You will notice the difference every time you visit with your ant colony. Museum glass looks invisible!  95% glare reduction.
