I bought a colony yesterday and they're sitting in a THA mini-hearth There are five workers and some brood. Last night, I put a small amount of honey and a dried mealworm in the outworld for them. The girls went to work burying the honey and half of the mealworm. I can't tell if they're eating any of the animal protein, I don't want to leave it in the outworld for too long. It is dried, so mold isn't a huge concern but... since they like burying stuff, I think I'm going to need to add some substrate into the outworld each time I give them food.
When I got home today, the queen was standing in the outworld, looking over her territory. I wasn't expecting to see her up there, but then the entire room was dark so there's no reason for her not to.
There also seems to be a far greater amount of material with which they have buried the food stuffs, are they capable of ripping up the formicarium material?
I think I'm going to put aquarium sand, in small amounts, in their food dish along with whatever culinary offerings I give them. When they're ready to move into a larger formicarium and outworld, I kinda want to give them some gold flakes to decorate with. Some of that desert feel, ya know.
One in particular is upset about the fluon barrier I added. She keeps trying to crawl up to rest upside down on the lid of the outworld.
