Stomatella or slug

[reefing1]

Hi reefers, i don't normally check the tank after all lights are out. Usually I spotted a couple massive bristleworm but this guy is new.
Is it stomatella snail or elephant slug? Thank you.

The bristleworm worth a share of its massiveness.

Just read through common hitchhikers thread, Im 70% sure its stomatella. When I'm watching it seems like its eating on the algae
