ID help!!
 

I put a rock into my fuge from my display last week and was just checking out the life before the lights came on in a fuge and found this creepy looking thing. It had about 6 long tentacles which looked to be coming out of its head and when I shone the light on it to get a better look they slowly retracted. Does anybody have any idea what this is!Attachment 9592

Bump

It's kinda hard to make out in the photo. How big is it, what kinda coloring as well? Also does it stay in one spot or move?

It's about an inch tall at least that's all I can see of it. I got a better picture of it. It's grayish brown with white spots in itAttachment 9603

It seems to be staying in one spot as well however it clearly is light sensitive and moves when a bright light is shone on it

It looks like a kind of sea cucumber to me. I had my suspicions with the first pic but the second clears it up.

to me it looks almost like a sea apple-could potentially kill your whole tank

Can anybody else confirm this? I want to make sure its harmful before I rip my fuge apart to get it.

I'm vote for sea cucumber but I will also say that most things that are poisonous are brightly colored. I'd hazard a guess that this is likely harmless.

Just my two cents though.

I agree with christy, except for the harmless part, kinda.
the way I see it is if you don't know what it is don't trust it.
lol that applies to reefing by the way nothing else.

Maybe the one at the bottom of the page??

Stating to think that it's a cucumber. However I can seem to find what kind it is. Does anybody have a good invert identification data base that they use?

Sea cucumber gets my vote, too.

I think the only real risk is if it dies, or barfs up its internal organ. It could poison your whole tank. I would remove it for that reason alone, but my risk acceptance is pretty low.
