Killing my crabs

What is this thing and did it kill my crab, reef tank

Looks like it could be an oenone fulgida- they usually eat snails and molluscs but apparently they'll eat crabs too- unfortunately they are very difficult to kill/trap

My crabs molt a lot - are you sure its a corpse and not a molting? To me, the orange creature looks more like a bristle worm scavenging the remains, rather than a cause of death (or molting).

Not sure, ima pull out all the worms, plenty of other cleaners in there just to play it safe, my local fish guy said there bristle worms also

Dead crab, not sure how it died, it may have been the hitchhiker from the initial setup I started with a little over 100lbs of live rock found him in the bottom of the box during setup so 0 acclimation for that little guy.

I know I’m months late but was the crab covered in slime? And did the worm instantly go back into its hole if disturbed?

How so?

 

[Hadla]

How so?

I think cause bristle worms eat whatever falls into the substrate like detritus so if you completely eradicate them, there’s an overload of ammonia/nitrites/etc
