Fire Shrimp injury or molting issue?

[pmcgillbsa]

Hello so my fire shrimp has a plate of his exoskeloton missing on his back (see pic). I'm not sure if its an injury or if he had an issue when molting which he just did the other day. He is doing fine and is acting completely normal like nothing is wrong. Is there anything I can do to help him through this? Water parameters: Ammonia: 0, nitrites 0, pH 8.4, Nitrates: 0, temp 77-80F. Thanks so much for your help

I wouldn't do anything specific to help him, but I would verify the Iodine content in your water.
Iodine is used in molting. I'd do an ICP rather than test manually, because its a hard test and you won't run it often. It will give you an idea what to add. Be cautious the amount as it can be over dosed.
