worm

Would love to know what this is and if it needs to be removed. Never seen it before and haven't added anything to the tank in the last 6 months. thanks :)

Hypothetically if you were Australian and you were struggling for months to find a distributor in your country to purchase a specific Nudibranch you have researched in depth, and it is illegal to import pretty much all marine animals in Australia without a license. And you didn't want a license...

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

I have just caught this one in the picture. It is in a drop of water so quite small maybe 5mm. One side looks like feather of some sort so could be a baby feature duster in loose

Need your help. Is this a this a parasite or tube worm? I find more little white tubes on my life rocks... shall I keep them or remove?

Stationary tentacle or worm, nocturnal, rapidly shrinks in bright light to what basically just looks like a pebble of sand stuck in a some snail slime. Edit: not sure the video is going to work so here are stills

Hi Experts, noticed this hanging out of a hole in a rock. It is only about 2.5cm and didn't move much. Didn't get the chance to see rest of the body part (hidden in the hole). Could it be a baby brittle star or is it a worm? Thanks.

So I’m doing some maintenance today and I was moving my chalice when I noticed this growth on it. I’ve seen these guys on a rock I have in my sump that has fan worms on it so I figured they were baby worms until I saw them on the skeleton of my chalice. One was heavily infested while the others...

Hey guys, I’ve had these small zoas for a couple of weeks in my new tank. They’ve been dipped with “the dip” by fauna marin and then inserted in the aquarium. After a day, they started thriving and some polyps doubled already in size. However, its been a few days since many polyps haven’t...

Below is from a slightly older post but everything still applies plus I added a scarlet skunk cleaner shrimp. I have a 14 gallon cube currently with a pair of young percula clownfish (one is probably 2 inches or so and the other might be 1.5ish), as well as several hermit crabs and snails, with...

Noticed a few of these little buggers going in and out of tiny holes on my Hammer coral. Are they harmful? Thank you!

Small colony of semi translucent tubes on a piece of rock I bought from the lfs. Each polyp seems to have exactly 4 appendages with nodes near the tips.

Can someone please tell me what this is??

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?

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 cleaning my filter today and found these all over my bioballs in my filter. Does anyone know what they are and what I should do about them?

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!

Hi any ideas? I’m new here and recently upgraded to a 75g mixed reef after my 30 nano exploded all over my living room. Not usually bothered by these but they were brushing up on that white part of my new monti frag. Are these just baby bristle worms? They are super tiny and seem to just wave...

I need your help! What are these tiny worms? I noticed a ton if these smaller worms, there are thousands of them. Looking for an ID on them.

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'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...

The last few days i've noticed a bunch of pen tip sized white spots pop up on my glass. I managed to get a pretty good picture of it. Are these baby snails or some type of worm? It looks like a shell.

Sorry the pics bad, it retreated before I could get a good one It's white, has a black stripes down it, and is slender
