I have a C. sansabeanus colony at around 30 workers. I finally decided to move them out of a very small test tube into a THA Fortress. It's been about 3 days and they don't seem to want to live in the THA Fortress chambers but rather in its outworld. The queen and all workers hang out in a corner of the outworld standing over all the eggs, larvae, and pupae. Occasionally, one or two workers will go into the nest to roam about before leaving, and at times the eggs may be scattered everywhere in the outworld but are eventually collected.
I followed instructions and research with the seller, on this forum, as well as informational videos on YouTube. Wondering why the colony won't move into the nest but rather reside in the outworld...
THA Fortress Nest:
-Water dish filled 2/3s for moisture
-Has one ventilation tube
-Has heat cable in 1 corner to create a heat gradient
-No garbage/trash seen inside any chamber
-Does not have red tape/film to block out light, but I turn the nest to a darker area of the room to minimize light
THA Fortress Outworld:
-Has water and sugar water tower
-Has feeding dish (uneaten food cleaned regularly)
-Does not have red tape/film to block out light, however, it's always bright because its usually facing the area of the room with most light
