I decided to move our T's from the kitchen to a darkish corner in the study. Definite change in the oldest one's behaviour.
The study gets far less traffic and light and noise etc. Our B. Albopilosum who recently molted is way more daring and now actually spends time outside its burrow and we can look at him without him running away, even at night with a torch.
The B. Vagans slings are also not hiding away as much and I can see them sitting ontop of their substrate when using a torch from below the container, although they are very skittish, dont blame them they are still very small.
Now I just need a solution to up the humidity for them all.
