Hello forum! Just sharing with you a few pics of one of my colonies of Prorhinotermes canalifrons, an interesting termite that takes very well to captivity. This is a fragment colony obtained by isolating a group of workers (more precisely pseudergates in this genus) and have them molt into secondary royals and breed, something that Prorhinotermes do very well. They are housed in a simple petri dish setup consisting of a thin slice of spruce kept a few mm from the bottom (and held secured) by a ring of cotton, plus a bit of soil.
A general look of the setup with some cotton removed and the spruce slice flipped:
