Looks like some type of flatworm.

It might be. I’m not sure!

So odd and it’s just sitting stationary. I want to assume it’s dead, whatever it is, but I hate making assumptions. Especially in this hobby

A worm was my guess. Just looked way too fat and big but I have hardly any experience with worms aside from bristles

 

[Lost in the Sauce]

Does it have a shell or soft outside?

Is it stationary or still moving? That thing is huge I have no idea how it would have been in your tank this whole time..

Looks like a tube worm out of its tube that expelled its feather duster

 

[Uzidaisies]

Looks like a cucumber that's having a real bad day. Not sure though.

 

[jgirardnrg]

I'd scoop it up and put it in an acclimation box or something to see what it does.

Might be on to something there.

It soft. Stationary. It’s enormous I have no idea how it’s been in here this whole time

 

[MaxTremors]

Looks like a scrunched up bristle worm (a big one).

 

[Udest]

Yeah I was about to say it looks like some sort of polychelate worm.

 

[Uzidaisies]

It soft. Stationary. It’s enormous I have no idea how it’s been in here this whole time

did you have any feather dusters?

 

[Jaden9933]

I have a feather duster but it’s crown is still there. It was near the tube of the worm though.

Picture for size reference. Not sure if that helps at all

You mean like how people had no idea a 3 foot worm was living in their tank without knowing until fish and corals started to go missing. LOL I'm trying not to be surprised (or freaked out) by this hobby anymore. So different than freshwater. Sea monsters are real! Haha.

 

[Bume]

Stomatella perhaps?

 

[Uzidaisies]

I think @G Santana might be right. It really does look like a tube worm. Is the crown opening at all? Maybe the worm dropped its crown, the crown is stuck on the tube, and the worm crawled out and is dying. I don't know if it's plausible. But i choose to believe it. lol
