Hey guys, newbe ant keeper here. About a month ago,I purchaced the beginner set antcube from antucube.de and a test tube containing a lasius niger queen and 10 workers. When it arrived i released them in the formicarium. Now i know that i should of waited till the colony grew bigger in the tube before i released them. I supply them with honey, apples, water and sugar water. a few weeks in, the queen moved out of the test tube into the formicarium. About a week later, i noticed that 6 ants were constantly stuck to the water tower. I found this strange. The next day i found 6 dead ants! Is this normal? I keep the humidity and temperature at a comfortable level according to Google.. I don't know what I'm doing wrong. How can i save the colony? Thanks
