Naked (something very rarely seen)
As said by Lydia Janssen, molting is a necessary but stressful process for a fiddler crab, as it takes significant energy and puts him at risk to predators or tank mates.
Fiddler crabs have a hard exoskeleton to protects them from predators, but it also restricts their growth.When fiddler crabs grow too large for their current shell, they will molt and form a new larger one, giving them the space to expand. Fiddlers can also use a molt to get rid of harmful toxins, which concentrate in the chitin, or regrow lost limbs. (Read: Lydia Janssen)
The average fiddler crab will molt around every eight weeks, although younger crabs may molt more often due to faster growth rates. The epidermis will begin separating from the cuticle about 10 days before your crab sheds his exoskeleton. The actual shedding process only takes around 15 minutes for most crabs, while the hardening of the new shell can take several days. (Read: Lydia Janssen)
