Well.. I found one.. a murder worm! I think..

[Schulks]

I wasn't sure what it was but it was just over a sand hill. I could see like 2 cm long finger leather looking strings that were extending and then curling back down. I studied it and tried to take a picture but couldn't. I couldn't see the pit of it because of the sand. I should have turned off my return and looked from above.. I tested if it would respond to shadows. It did not. I decided to try and scoop it out with a little measuring scoop as I was uncertain it was a worm. When I went for it; it was too close to the rock and it receded back down into the sand and probably that rock. I had only a bit of sand.

I have 55 lbs of gulf live rock. I am about to search up some worms..

The bobbit or eunice worm. They can eat your fish if they get big enough.

It already came back out and I have a good video to share once it is done downloading. The picture is unclear but the video will help. This doesn't look like a google image of a bobbit but I think it is a eunice worm.

Oh wow, I was just reading about those , says they can permanently cause numbness if they bite you. I hope you get it out!

Here is the video of mine. Near the end my royal gramma scares it and you can see it react.

it is definitely filter feeding with those bushy things but the bottom looks like a scary mouth.

Remove it

Remove it

I am not sure how. It must be connected to the rock beside it so I could just take that rock out but i like that rock lol

I also remembered this which is another possible worm. I'm not sure if they are because these rocks aren't large. I always thought this one was some kind of algae but with how the other is behaving and looks I am not sure.

i would just remove the rock and remove it as soon as possible before one of your fish gets hurt.

The live rock is just too expensive to toss. I'll put them in another aquarium and figure it out i guess.

Maybe pull the rock and see if you can get it out with the rock out of the tank. Maybe squirt something in the hole that may drive it out?

I can’t see the video for some reason but based on the still images, I don’t think that’s a bobbit. Looks like the “frond end” (not sure the technical term) of a sea cucumber

That actually sounds right but I am not a cucumber expert. I am going to my LFS and will see what they think.

You don’t have to throw it out. There’s a few ways you get get it out.

This looks VERY much like a sea cucumber

Yeah. That makes a lot more sense. I believe you're right.

Be sure to apologize to it :)

I am thinking sea cucumber on both also. Not sure on the first one 100% but the second one is sea cucumber.

Do some cucumbers attach to rocks or stay in one place for months? I remember looking at the second one in the same place awhile ago. The first one is still in the same spot as well.

Edit: also would a eunice worm react to me blocking the light/ a big shadow? I assume a cucumber would not respond and what I have does not respond.

Bobbit worm or Eunice makes nice tunnels within the rock, you can’t pull them out. I had one in Tonga live rock, it ate expensive corals over a couple nights, clams, scolys and rhyzos. Broke the rock apart with hammer and chisel, it was very long, dark and nasty.
