Did I kill my snail?

[Fishkeeper01]

I was doing aquarium maintenance and needed to move the tiger nerite snail.

I tried just pulling him off, until I felt like I was damaging him. It felt like his shell moved a little, but he did not. I immediately stopped. He is moving around still, but I’m not sure if he will survive. Here is a pre-pull picture:

And a post-pull picture:


Does it look like the snail is separated from the shell? I’m not sure.

Thanks in advance for any help.

The second photo is kind of blurred but it seems like it has been disconnected from the shell compared to the first picture.

I feel like it's kind of disconnected from the shell.
