One of my first queens has been amassing a nice group of workers. I have been feeding them crumbs of dry cat food. Currently I count approximately 10 workers and an unknown number of eggs / larvae / pupae. This is my first colony, and I'm not sure when I should think about moving them to a formicarium. Also what are your opinions as to what type of formicarium is best for a beginner?
Here is a picture of her growing colony
