A formicarium for expanding colonies

With organic forms and our unique connector AntGate this series of formicariums stands in a class of its own. Perfectly fits other AntKeep sizes for easy expansion! Invented in Sweden.


AntKeep is our own formicarium. With organic forms and our unique connector AntGate this series of formicariums stands in a class of its own.

Acrylic layers – Perfect for keeping ants
Four acrylic plates of extremely high quality make up the structure of the formicarium. Three white layers in the bottom build the foundation. And with a clear layer on top you can see everything happening in the ant colony.

Sponge for moisture
Thanks to the layered structure it is possible to moisturize AntKeep without opening it up. By filling the sponge with water the nest will be moisturized. Through laser cut ventilation canals in-between the layers the moisture travels from the sponge and out into the nest.

Why the form factor?
With the organic forms of AntKeep we wanted the nest to feel inspired by nature, in which there are very few straight lines. A lot of curves mimics the way ants dig through the terrain in the wild.

Expand with your colony
When your colony grows bigger so should their nest. AntKeep is easy to expand by adding more pieces from the collection. The sizes fit perfectly together, but you can also twist and turn them to create your own nest shapes. Experiment and you will find that many, many AntKeeps can be added upon each other, creating you own custom nest.

AntGate – Our unique connector
AntGate is the pinnacle of antkeeping. With AntGate you can easily and seamlessly connect AntKeeps, tubing and test tubes. It is made from a hard but flexible rubber-like material, meaning it will keep your AntKeeps tightly together with ease. And hey, the material is 100% safe for your ants.
