Empire of Ants Limestone
The Limestone formicarium from Empire of Ants is perfect for medium to large sized ants. It is a naked formicarium so you can design the outworld to your own specifications.
A connection port on the side of the nest allows you to connect another nest area or outworld if required.
Like most YTONG/Hebel nests, these will need to be watered to maintain the humidity level inside.
