I believe I have a problem with my Lasius niger colony.
The colony is housed in a test tube within an outworld. I believe the ants have been stacking their waste against the cotton of the water reservoir. This led to the cotton ball becoming green, but I thought nothing of it because Iv'e read it wouldn't be a problem. However, the water in the reservoir is now coloured red. I thought this was alarming, so I'm coming to you guys for help. I've tried moving them with light and heat already. I have even shaken the queen from the tube into the outworld, and she quickly took shelter into a new testtube. However, the ants would not follow her and after an hour she moved back into the brightly lit testtube. I'm getting desperate now. I really don't want to lose this colony as it's my first ever and I have grown quite attached to it. Help me please!
In reality the water is a little more red than the pictures show.
