You can keep ants in a lot of different habit some people prefer larger habitats e.g fish tanks (ME) and others prefer smaller housing e.g The well know traditional Ant World but the choice is yours.

Feeding:
Ants can be fed on small invertabrates such as flies and fruits. I would also recommend Mrym's Ant jelly their is a link on my website to his website (Ant Nest).
