Death after molt

What are your parameters? What else do you have in the tank besides the emerald crab? Things die for unknown reasons all the time, the fact that it died a couple days after a molt could just be a coincidence.
Shrimp, crabs need iodine in their body for molting and forming new exoskeletons. If their iodine level is too low, that can cause a "bad molt" and they die.
Doing regular WCs usually provides all the iodide (ion state of iodine) that your animals need. However, if you are lax on WCs then you might want to consider dosing iodide. However, I would only do this using a test kit. Too much iodine is toxic. You never want to exceed 0.08ppm (max concentration found in natural seawater.)

My crab was in a 10 gal QT tank with 2 cinnamon clowns and 3 small hermit crabs. I do a 1 gallon water change every 1-3 days, parameters all normal except when I did last water change, just before I noticed the molt my salinity was higher than normal and I may have dropped it to rapidly, could this be the problem?
