Tiny black "slug"? Only comes out at night.

Just got home from a late shift at work and saw this dude while checking the rocks with a flashlight. It retreated when I shined the light on it. It looks slug-ish. Any idea what it is and if it is reef safe?

possibly elephant slug , reef safe ,kinda rare nowadays...

I found 2 more, one tiny one on a rock and a bigger one (2-3cm) hiding under a soft coral that closed up when I shined the flashlight at it for too long.
