Snail? Slug? ?

[TikiBird]

Peeked at my reef tank tonight and was surprised to find this little critter on the glass. It worked its way up to the lid and I took this video.
From looking at pics, it kind of looks like a stomatella snail? Only I didn't see a shell? [emoji848] Any ideas?

Looks like Stomatella.

Agreed.
