Hi guys.
I built this formicarium myself out of Y-tong aerated concrete. This is the first time I have seen mold in the formicarium and its spread fast.
They havent dragged any food into there so I have no idea what has set it off :S.
Is there a safe way to remove the mold without harming the ants? or do I have to move them out get a fresh piece of ytong and start again..?
Please Help. My other formicarium seems fine its only on this side of the formicarium up the top which I have been trying to remove with a qtip and down the bottom which I cannot get to..
