Hey all. Can anyone id these green tubes and is the red on the rocks coralline algae or red slime?

Hi

Those are vermetid snails and those are awful get something to get rid of them immediately.
The algae looks like red slime IMHO.

Ugh …that rock appears to have hundreds of vermetid snails. Bad news. I’d pull that whole rock and bury in the back yard.
