I set up a 10 gal aquarium as a vivarium for a mature Camponotus colony. I am a novice ant-keeper, but a quick learner. I set up a small water reservoir in the front right corner (I've set up vivariums before, so no need to worry about there being something wrong with the aesthetic or mechanical aspects of it. It's just formicariums I'm new to), and I'm wondering if I need any water test tubes in the tank as well. I included some pictures for context. Also, any tips on feeding?
This one is the most helpful image:
The colony lives inside the log depicted in the back of the vivarium. The water looks a little murky in this shot, but there are no harmful substances in it. Also, all the plant life, ants, and substrate is locally sourced, so no worry there. Any suggestions are helpful, as I am new to the hobby. I actually discovered this colony completely by accident!
