Square Outworld 2.0

The Square Outworld 2.0 is the perfect upgraded foraging arena for younger/medium-sized colonies. It is 3x3x3 inches with a bottom ultracal filling for grip. The ultracal filling reaches up the side of the outworld to provide a grip for the ants to run down from the tubing port. The lid has a mesh ventilation hole that offers airflow, establishing the outworld as the area to forage for the ants and helping to prevent mold growth.
