I am sorry, what is a palp again?
And I have more to report!

It is actually out during the day and I've seen it around for awhile. I thought it was a mushroom..



Edit: and where it is now, I will be able to get really good pictures tonight when it opens up again.

The two little strands used to seek food

I don't think it has palps but I will have much better pictures soon.
I think you see a large brittle star waving its arms in the video.

It moved to a much better spot. Once the lights are off I will sneak up on it with the camera.

My cleaner shrimp died this morning, he was a few months younger than my clowns which were my first fish . He was in a hole in a rock so I figured my pistol shrimp had him. But! I have liverock so I'm paranoid of worms.
I took my flashlight around the tank just now and found a thing..

I could not get my camera to focus so the video is very bad. The angle was just terrible. I also could not see it well but I'm not positive it has a mouth. It almost looked like a wierd anemone to me. It is about 2 inches in diameter

I have no idea what it is. But the video might demonstrate behavior some. I tried to get it to respond to brine and it went under.. If it is a worm. It is huge.

From 20seconds to 57 seconds nothing happens so skip.

I'd say it is a Bristle Worm. They do sting so be careful. They are listed as Reef Safe With Caution. I have them in one of my smaller tanks and I still don't know what to think of them. They do multiply like crazy. They can look very small and then they start to stretch out and oh my gosh - they can be very long. At first they would be in the sand which I was ok with. Now they like to be inside of caves in the rocks. I was hoping my Pistol
Shrimp would eat it but no such luck, even though they continue to be in his tunnels. They are very fast and almost impossible to catch. When you think you have them in long tweezers, they shrink down to almost nothing and are gone. I'm still not sure if they effect the corals or not because it is a smaller thank and I don't know if the corals in that tank don't like the size or lighting, etc. or if the Bristle Worms are getting to them. I'm still trying to experiment and figure that out. If they are in your rocks, you might be able to take that rock out of the tank and have them still stay inside the rock. If you have a small tank you might want to take the rock with them out and put it into a small tank and watch them. When I feed the fish, they come out and grab the food and they seem to eat just about anything I put in there. They have left the fish I have that partners with the Pistol Shrimp alone and again, they are all in the rocks and caves together.

I have posted some more pictures throughout the thread. It is sadly, not a bristle worm.

If your bristleworms are taking over; I have heard arrow crabs will eat them but I am not sure of their risks.

My brothers 40 gal tank had a lot of bristle worms. The goby and pistol shrimp cleaned them out to the point of extinction almost.

 

[Schulks]

This might be anti climatic.
It looks like an aptasia.
I think these pictures will convince you it a worm.



And this video to show it is really a wierd exotic aptasia of some kind.



The video shows it shriveling up to the light. I tested on an aptasia and it does the exact same. I had no idea aptasia would react to my flashlight like this.

What is the white circle with ragged edges that it leaves on the surface all day? It takes the circle under the sand with it. It also prefers under the sand. I haven't seen the circle on any rocks.

 

[JonoH]

Is it a Majano?

 

[JonoH]

Actually looks a bit like a Gem Sea Anenome

 

[Schulks]

Majanos are small right? I think this is too big.

And my rocks are from the gulf of america. I don't think gem sea anemones are found there.

I think this picture is key to identifying it. Other anemones don't have this.
The tentacles retract/extend from the center of it. In this picture it is has sand in the middle of it.

 

[Schulks]

There is just too much to learn in this hobby.
I just read about long tentacle anemones.

Final answer: sand anemone - read they have an oral disk that stays above the sand.

Now what to do with it. Treat it like aiptasia or see what it can become? lol

I think it is a grey sea anemone but it could be a "tube-dwelling anemone".

That is what I was hoping for but so far, neither the Pistol Shrimp or the Goby touch them.

As long as they eat other food, they will not go out of their way to hunt the bristles.
