Ok, in one of my lasius niger testtube and one of my tetramorium ceaspitium testtube has the cotton turned black. Do anyone know why this may have happent and should i maby move them?
Yeah, you can move them. most test tube molds aren't dangerous, but its better to be safe than sorry. It was probably a result of not properly cleaning your equipment or hands.
