The tank has 2 islands, one for the nest box, one for the food. Heat and humidity is provided by pouring around 7cm of water into the bottom of the tank and heating it to around 30C. The addition of a small pump ensures the ants will not escape. When the colony grows very large the whole tank can be filled with soil and the top moat becomes the escape proofing.
It is easy to replicate this idea using a normal aquarium, two bricks and a container for the nest. [/img]
