Tiny black blobs

[Forty-Two]

Hi - not sure what this is in the tank. I do have live rock but these are appearing only on the dry rock. They move very slowly, but perceptibly. They don’t appear to be worms. No they aren’t holes they seem to move across the rock and also are able to lift themselves up.

Pics a bit fuzzy to confirm but May be elephant slugs, black stomatella or other mollusks

Thanks. Yes they are very small and I only have the iPhone camera at this time. I’ll keep an eye on them to see if I can see tentacles or not
