For a colony of smallish ants that size, there is no reason why a GroTube wouldn't work.
For $39 and free shipping, you get a durable, reusable formicarium with detachable foraging area, complete food kit with different Formula foods to try as well as a glass beaker and silicone mold to prepare them, as well as 3 liquid feeders, and 6 different kinds of materials to either customize the foraging area floor or allow the ants to bring them in and customize their nest.
It's a kit to give someone everything they need to get started with their small colony in the world of antkeeping.
You can see a live stream of a colony living in a GroTube, here on YouTube.
Unlike many formicaries where the chambers are oriented along a wall vertically, creating caverns that you must use a flashlight to see inside, the GroTube is designed for maximum visibility, allowing you to see your ants and the inner-workings of the colony close-up to the glass, and more clearly than any other product available.
I will say some people who have started with a single queen or only had 1 or 2 workers have had problems with the GroTube. But with a colony of 5-10 workers and a queen—that is what I started the one on the YouTube video with about 2 months ago, and now they have 20 workers and are still growing.
Because the lid is removable on the GroTube, you will be able to clean and reuse it with any colonies you have in the future for years and years.
If you have any questions about the GroTube, I and others would be more than happy to answer them here.
