I recieved a colony of these yesterday, it consists of 1 queen & 2000 workers. They're being kept in a 4'x2'x2' custom made tank with about 1' deep of soil, rotten leaves, twigs and a couple artificial nests which seemed to have been ignored by the ants. Once put in the tank the ants came out straight away and a soldier seemed to be scouting the tank and I think it started two highways, after these two highways were created another one started near the front of the tank and they were taking bits of live food back but were also burying some of it near the the tube. Some of the workers stayed at the test tube building soil up around the entrance of it and made a smaller entrance. About 2 hours after these highways were made, two of them stopped, and one became less active but was still going, this highway soon became very active and the ants later moved the nest under a pile of leaves. There was some massive brood being carried to the new nest and I seen a couple big soldiers but unfortunately didn't get to see the queen. Now today I found the new nest seemed to have very little activity with only a couple workers coming out every couple of minutes to go some where else, watching these workers they walked about 1' away from the new nest to where there were hundreds of workers digging under another pile of leaves. At the moment they have stopped foraging but i've been told they may stop for a couple of days. This is all i've seen from yesterday to now, they are still digging at what I think could be a new nest but I will update if anything more happens. Also here are some pics of the setup, also some of the larvae, in some of the pics the ants cannot be seen but i'll try my camera to see if I can get it to focus on them.
In this second picture you can see the test tube, and to the right of it are the pile of leaves they moved to last night. But now they're currently working on the hole just below the test tube.
Here's the picture where the workers are carrying the big larvae, it took about 3 or 4 workers to carry each of these.
