Lethargic Porcelain Crab - Molting?

[leezard]

So he's upside down and very much not moving, with the exception of the current rocking him back and forth. I've left him there for the time being in hopes of their molts being similar to tarantulas, in which they really do flip upside down and pretty much mimic death.

Advice would be very much appreciated.

Thanks!
