If you make the farm so small you should be able to see some of the rooms but the ants will use the sand to make it dark, they probably going to stick it to the glass.
But it is worth a try, place some pictures if you finished it.
In Europe there are not really import rules, it is illegal to let species from an other country free but as for as i know you may import them.
Camponotus gigas Very nice ants, but hard to keep, if you have more than one queen, I'm always interested.
