Is there a such thing as too humid?

My crabitat keeps going up to 96% humidity. Have been opening it and not misting it unless I leave it cracked so long that it falls below 80% which takes forever to happen. I think its just the baths and glass lid. Is this a danger to them? Temp stays between 80& 85. Purple pinchers.

High humidity is safe for crabs. It won't hurt them.

There are some possible downside to high humidity you need to watch for. Condensation on the inside of the tank. Eventually it can cause droplets of water to form and run down the glass into your substrate. Over months that can cause a build up of water in substrate eventually causing flooding. Super high humidity will also not and mold food quicker too.
