Crab sleeping from screen lid

[Crusty12]

My hermit crab has never done this before but he Is sleeping i believe upside down on my screen lid. Is this normal? I never had a hermit crab do this before but one time I did catch him sleeping in the plants up high. He has places to get down and he was fine this morning and I do have plastic wrap on the lid temp and humidity are fine. Just wanted to know if I should be concerned.

He should be ok. Many crabs will find a way to get to the highest point in the tank, and mine have stayed there all day sometimes. He will also likely be ok of he falls, as many crabs in captivity have fallen from second levels and walked away unscathed. Just make sure he can't escape.
