Nice work, man! My Tetramorium are absolutely exploding, too. They've been in this bead container formicarium I made for over a month, and I'm thinking they will soon need another extra large one! I have a second big colony still in a mini-fridge that I'm hesitant to take out because I don't know how I'll keep up with two huge colonies. Basically, I'll just need to install more shelves up in my house and soon!
