Cohabitation
Keep as a colony, one per enclosure. These animals naturally live in groups and cope poorly alone. Never combine two colonies - foreign individuals are not readily accepted but fought. Watch food and humidity as the colony grows.

Notes

Like Acromyrmex, but on a different scale: a mature colony processes considerable quantities of leaves daily and needs several chambers. The leaf supply in winter is where most attempts at keeping it fail — work it out honestly beforehand.
