I buy this colony on 10 April on antstore.
After six weeks:
My formicarium is made of polystyrene boxes connected with plastic tubes.
On bottom i put some ytong for keep it humid
I bought these boxes on Hyperlinks sind nur für registrierte Nutzer sichtbar, quite cheap 100 for 30 euro, the size is 95x65x45mm
In these days they are moving from the tube to the first plastic box
