Cleaner shrimp suddenly death :(

[JcK03]

Hello all ! It's me again.. short description, my reef is 1ish month old, totally cycled, with 1 pair of clownfish and a Midas blenny. I'm currently in the ugly stage with lot of diatom on sandbed and on my rock (you can see it in my last thread)
This morning, I have found my cleaner shrimp dead laying on the sandbed
Yesterday just before I was going to bed, she was eating her little mysis like usual.
She have molted Monday of this week, and she like going really fine in the next days, eating, thriving and all.
When I have receive the shrimp, she seems to have eggs (maybe it was not egg finally? I post a pic from what I was thinking of eggs)

So I'm wondering what can be the cause of her death...I'm thinking about a possibly lack of iodine cause my reef is pretty new ?
I have a mini carpet anemone too (was given for free and was thinking it's an hairy mush lol) maybe it have sting the shrimp ?
I have a lid too, maybe the shrimp have jump and stay stuck in the lid?

Shrimps are more sensitive to water parameters than fish. Your tank is still very new also so maybe there just isn’t enough food for it.

Wait a few months before you add more shrimps. Also, the tank being new, you don’t need to be dosing anything yet. Just do weekly water changes and that will help.

Ok thank you. But I'm target feeding her 2 times a day with mysis, so I'm not think she was starving ? And I'm dosing all-for-reef because (don't hate me plz) I have already some corals to take care !
