I'm new to tarantula keeping, but prior to getting them I watched most all of Tom Moran and Tarantula Collective's video's on them to educate myself. The thing I liked was that they were fine to keep with no added heat. My house is always on the cold side during the winter/spring/fall and lots of times at night gets as low as 66. During the day though it is 68-70 ish Now I have a few slings and a 1.5" GBB They all seem like they are doing well in these temps but the GBB doesn't move. She molted 9 days ago and still hasn't moved from her spot...I'm worried that it maybe a little chilly for her and that's why??? Do I need to worry?? Thanks!
