Please post here if you are a new crab owner and someone will be along shortly to welcome you to the HCA! This is also the place to welcome new crabbies to your clan!
I do have my two UTHs insulated. My insulation covers the whole back and one side. I think one of them is too small, I should probably replace it with a larger size.
Are the ultratherms insulatable? My house gets quite cold in the winter, so I need to be able to wrap them.
I'm relieved to hear that I can't really overhumidify them
