Did I entomb my Nas snails?

[Glass Algae]

Recently scooted over a rock and added a small middle one to make a shelf look (pbefore and after Pics below)

Two days prior I got nasarius snails and they all buried except one one odd Boi who I think may die soon as he doesn't move and is half buried.

Anyway when I feed sometimes I see this one Nas snails rise up and clean some substrate but have only seen one other besides sick Boi.

Did I entomb my snails to the most nefarious of fates?

The two small rocks are resting on the substrate now for reference. I think the big rock is the only one meeting glass.

That's what I was hoping as at first I watched then crawl around from the under view of my tank and they were quick Lil snails! The cleaner is such a good shrimp he hangs out on my hand as I move stuff around the tank he's never in the way always on my hand if hands in the tank. ☺

Ty for the Input!
