What do you do if your hermit crab is sick?

Though there are few illnesses that a hermit crab gets you can tell when your hermit crab is in distress by a few symptoms.

1. Streaking - a hermit crab does not leave it's shell unless something is wrong.

2. Dropping Limbs - this is not a normal behavior, if your hermit crab has dropped limbs something is wrong.

3. Not moving/sluggish movement. Going into a hibernative state is a reaction to something being wrong, usually in the environment such as low humidity/temperature.
