Sea cucumber ID

[mww00ds]

So I got some live rock from Gulf Live Rock back in November. Since it's arrival I've been seeing these arms poking out 9f the rocks. Pretty sure there is atleast 2 different cumbers in the rocks. But haven't ever seen anything but their arms out in the water column catching food. Can anyone ID this species so I can find out what I need to do to keep them alive. The mouth is roughly the size of pencil eraser, with the arms stretching out to around an inch in length.

I can’t see the video, but my guess would be
Pseudothyone belli

Likely sea cucumber yes, and will need to sea body to say what type, If I took a guess, either red or orange foot cucumber

Sadly the body never leaves the holes in the rocks.

In most cases that is correct. At least you inherited a good filter feeder
