hello all, i got a new piece of live rock and this came off of it. it looks kind of like some sort of sea slug. is this thing safe for my reef tank or no...

It looks more like a small sea cucumber than a slug.

 

[RicksReefs]

yup, cuke. I have a number of those same ones. they're usually pretty cryptic and rarely out in the open. it's a reef safe sediment feeder.

 

[Guygettnby]

so its some sort of sea cucumber?

 

[SNAKEMANVET]

If it has a shell that comes to a point it is a key hole limpet. They are reef safe.jmo

 

[Guygettnby]

this has no shell at all. the back of it has little suction cups and underneath it looks like a slug.
