Nest building: Soil nests
Carebara cf. diversa is often called the driver ant, even if it is not really a. This is due to the fact that it behaves in a similar way to driver's aids. Carebara cf. diversa sets very long to powerful lining streets. They attack every kind of insect by their surplus of workers. The powerful soldiers usually act to protect the colony with their small, slender workers. Partially, the workers also sit on the queen and the soldiers as they go. Large colonies are absolutely interesting. Their greed and hunting instinct is overwhelming. Here, a larger pool than an arena should be used at the beginning of the stance, as colonies can grow very quickly. Individual workers try to break out again and again by exploring weaknesses. Therefore, a good escape protection should be ensured. [/quote]

The book is more about the life of the author but contains good insight into the behaviour of the marauder ant. Is quite a nice book to read though. Especially if you're young and interested in ants.
Onto their temperature requirements. It is very high and more specific compared to most exotic species with a minimum recommended typically at 27 / 28 and a maximum of 30 degrees celcius. This makes it harder and more expensive (Questionably not much depending on equipment used) than your typical 24 - 28 degree celcius requirements found with many other species.
They have an omnivorous diet similar to that of say a species belonging to Pogonomyrmex in that they eat seeds, insects, meat and fruit however from what I've read into their behavior they seem to lean to wanting high sources of protein.
They do have stationary nests like most ant species as well however they can equally be described as a nomadic species in which they wish to move nests at a fast rate. No doubt because they typically seem to deplete their surroundings of sufficient resources. As you will be supplying the necessary resources for their survival this may not be such an issue and this behavior may well be suppressed. They do seem to have high risks of fungal and mite outbreaks however. Perhaps this is a fine art in nest making and maintaining the species never bothered to learn due to their happiness to venture elsewhere.
Personally if I were to keep them it would be in a very large tank filled with soil heated softly from below and heavily from the surface. This sort of set up would require a lot of equipment and effort to maintain but in my opinion be most appropriate. Likewise I would probably have a second tank to set up and have them move into then clean and recreate the first. Essentially doing constant rotation decided by them as to when.
For the founding you could probably get away fine with just using a standard small soil ant nest but you would have to judge well when they need upgrading. With large amounts of soil they can alter their nest environment to allow for better waste disposal, humidity retention and respectively ventilation which would help prevent mite, mold and fungal buildup.
I would imagine Carebara diversu is extremely difficult to keep once heading past the one year period if not after a couple of months but if you were to successfully keep them you would have the privilege to watch one of the most aggressive dominant species with fascinating behavior. Likewise though you'd probably be watching it mostly from the surface as a large basin soil set up would no doubt limit massively the amount of inner workings inside of the nest.
This is just my two pence on the issue anyway. I'm sure in regards to keeping someone with experience would be able to help you massively.
Just to add as well that your age is 13. I don't wish to mean this in a horrible manner but with your age and the added issues such as financial etc... that can arise because of it that the marauder ant is probably very ill suited to you and your money can be spent on a species which is not so difficult and demanding in environmental controls, dietary needs and escape prevention which I haven't even touched upon.
