Hello everyone, I decided it was time for me to build my first formicarium for my camponotus sanctus colony with 10 workers, basicly I went with an aquarium design I built the grout nest as you can see in this picture http://imgur.com/faw3bhl after it has Cured for a week im going to fill the rest of the aquarium with sand and then apply a layer of grout ontop to prevent the ants from digging into the sand. I really like how it looks so far what do you guys think ? Any suggestions ? And also I do not know a good way to prevent the ants to climbing the sides of the glass will vaseline or cooking oil work ? For camponotus ? They are insane climbers.
