i knew you would say that. you just have to realize if those ants escape they could do some serious damage whereas other exotic ants just would die.
Its a good start to set up a basin with a lid that is permanently fixed to the basin. you could for example duct tape it and remove the duct tape when you want to feed them. they also need a warm spot in their nest in order to produce soldiers. I would recommend a nest inside of the basin, not some kind of ytong or gypsum connected externally.
Those ants love to dig so if you do not want them to dig wherever they want you could cover the whole basin with a thin layer of gypsum. i found out they do not like oil at all but that might change when the colony is like 5000 ants.
If you want to give them sugar or honey make sure to only give them microscopic sized portions or they will just drown or stick in it due to their minimal size.

Loads of insects of course but some people give them plant seeds, too.
