Pheidole Megacephala Formicarium

[beau15415]

I have a young Pheidole Megacephala colony that I have just acquired with about 15 majors, 100 workers, a large pile of brood and 1 queen. I am creating a simple set up in a plastic container for them for now until I can buy an AntsCanada ant tower small. I only have some rocks and a couple centimetres of digging medium for them. Any suggestions on anything else to put in the setup or how to provide them water?
