worm id

Turned on the lights this morning and saw this. Anybody know what it is??

Hello all .. can you please ID this sl white worm .. is it good or bad .. please refer to the video

Not really familiar with this worm? Not sure what it is but I have several of them in my sump and was wondering if I should remove them or just let them be.

I just discovered about 7 of these little whispy white worms on the glass of my QT tank. Sorry I couldn't get a better pic, my camera refused to focus on them up close. They have 2 antennae and are about 1/4 inch long. Any idea what they are and are they something I need to treat for?

I just woke up to my fish tank and this is sitting in the front. Does anyone know what this is? What should I do? How do I get rid of it? Is it bad? Also don’t mind the algae I’m working on getting rid of it

Just wanted to verify if these were fireworms. Found a bunch underneath a clove rock I took out to clean. Any worry with corals or to look out for with more of them?

Noticed these in my tank today, what are they, are they dangerous should I remove them?

Good day all, my assumption this is a baby bristle worm but would like a confirmation or a different opinion. Mainly hoping it’s not a B-Word worm! Lol! Thanks in advance!

After searching in here for 3+ hours to identify this, it's time for my 1st post in hopes you can help me figure out what it is :) AIO 28g nano is 2 months cycled, live rock, 2 clown fish, cleaner shrimp currently. Showed itself 4 days ago... Olive Green color, about 1.5" seems to have grown...

Hi, I noticed my torch not looking good and saw these crawling around it. Can someone point me in the right direction here so I can start researching. Thank you!

So I know I have other issues I'm dealing with but I looked in the tank and seen this! I have no idea what it is or what I should do about it. Please help.

One last question. I had a couple of things growing on my euphyllia coral stems. Also some fishing line sized worm looking pests on my live rock that I took a polyp off of. Are these pests to be worried about? Thoughts? I really need some input, thanks!

Happy Super Bowl Sunday! I was getting through some weekend maintenance before the big game and noticed this black object embedded in some Zoas. Didn’t think much of it until I noticed it had little antennas. I’ve never seen a black worm/slug like this before. Any thoughts?

I Found this little creeper in my filter. Is this a harmless bristle worm or should it be voted off the reef? thoughts on ID? Thanks all!

This thing has been crawling around, feeling and spreading and retracting it’s hairy tentacles. What is it? and is it reef friendly? Thank you in advance!

I was doing some poking around to consider fragging some mushrooms and suddenly the mushroom retracted and shrunk, and seemed to spew these semi clear worm tentacles like things. Are these worms in the shrooms or the shrooms tentacles? Thank you all for your support and advice!

Hello All! I found this little white hairy black thing... any ideas? Aprox 1” The black portion was lightly covered by the substrate and the hairy bit was on the substrate surface flowing. It has not moved since its discovery an hour ago.

I found this critter today. I am not sure what it is. Good or bad? Should it be killed with fire? Seems like a small orange worm with small white tentacles, or hairs, on one end and pointy on the other end. I hope the pics help. Thank you for your help!

I was cleaning one of my tanks and decided I might want to do some reworking of the rock. All was fine until I moved one of the foundation pieces and ALL OF THESE LITTLE THINGS CAME SQUIGGLING OUT ALL OVER FROM UNDER THE FLAT PIECE. I thought it was bristleworms but they also kinda look like...

I have tons of these all over rock and want to know if their a pest, bad, or hurt anything? And if there’s any crab or fish to get rid of them. Setting up a bigger tank and I wanted to know if I should bleach the rock to get rid of them and start over

Hi guys, I have this super weird worm ive finally managed to catch. Its white and seems to swim really fast by wiggling quickly. Its superweird and havent seen anything like it Getting a good photo is hard since its never still. Anyone have an idea what this could be??

Sorry for the no pics in advance. I just noticed a long clear worm poking out from my live rock reaching up toward my Zoa. It retracted once the light hit it. Didn’t look like a bristle worm. Any chance it’s just a simple peanut worm or should I FW dip the live rock? So far as I can tell it’s...

I’ve seen some normal looking bristle worms in my aquarium but nothing like this almost hot pink looking one. Fireworm perhaps? How should I go about removal or is that even necessary? And sorry about pic quality i hope that doesn’t affect the ability to identify it.

I've just finished cleaning my tank out and noticed I have a few worms climbing around in my glass that I haven't seen before I am struggling to get identification on I have tried to look on lionfishlair to get an I'd but it won't load. Any help would be appreciated Not the easiest to take a...

This just showed up recently attached to the back wall of my QT tank. It is about the size of a dime. Any idea what this is? The arms move around a bit (front and side shots included).
