An ant plant is a special plant, with holes and chambers in its tuber. Ants can, of course, make good use of these. The plant also releases substances that the ants feed on, and in return, the ants provide the plant with protection.
Now grow your own ant plant to a size suitable for housing a Camponotus nicobarensis ant colony.
The plant has reached its proper size when holes have formed in the tuber; from then on, you can house a small colony in it.
