What is this!!??

I was looking at one of my live rocks tonight and I suddenly saw something like a slug crawling through it. It almost looks like a snail with no shell. Im posting a vid here. Its right below the hermit an you can see it slowly moving. What the heck is it!?

Hard to tell from vid but sure looks like a stomatella snail. Google it & you can see if that looks the same. If so it's a beneficial part of your CUC.

It looks like that could be what it is. Thanks!!

I have around 10 of those that I got from this one piece of live rock and they do some serious clean up. They have a straw or a trunk in the front right? Idk what they are, but I'm really happy they're in my tank.
