I moved my L. niger colony of 20 from a test tube setup to a formicarium bought on eBay.
Two days after the move the ants started having some kind of neurological problems: twitching, lying on back, not caring for brood, etc..
Basically they are dying off. Touching the workers does not move them from the spot, they get excited but seem unaware of their surrounding.
It looks like poisoning to me. I contacted the lady that makes the formicaria, and she assures me that all the materials used are ant safe and that she never had problems with them.
She seems to know her ants, and has sent me photos of large colonies thriving in formicaria of the same make. She also claims that the item was not stored in a warehouse with pest control or anything similar.
I am inclined to believe her. She seems concerned.
Could it be the shock of the move could do this to the colony? I did just dump them in the outworld (ashamed).
Anyway, here are some photos and videos. What do you think is going on?
