I have a dark blanket around the bottom of the tank to cover the substrate in case a molter is nearby. So no light will get in. Well I figured that their were no crabs in the front of the tank (they usually molt in the back of the tank. Against the wall. Besides it is more shallow in the front and mounded in the back. So I decided to take off the blanket and what do I find??? A molter on the left corner on the bottom of the tank right up against the glass. And this crab doesnt have an air pocket it has a room.Unfortunately it is below the water bowl of course about 4in below.owell,its safe. Anyway I took a real quick peeky and covered the front again. This was 2 days ago. I thought I would take another quick peek. No lights on just natural light in the shade. And it had just molted. He was in his shell with his little legs tucked loosely in. And his exo was next to him all intact. He had not eatten any yet. I'm going to wait about 2 days and then during the day I'm going to take a quick pic (no flash)and post it. It is awsome.
