worm id

I was turning off the lights in my aquarium when I spotted this white worm swimming in an S shape around my tank. I removed it because I have no clue what it is. I've seen bristle worms before but i've never seen them swim and i've never seen them in white. the worm's about 1 cm long. I've...

Got you — here’s a smoother, blog-ready version that keeps your tone but cleans it up and flows better: I’ve noticed these worms in my sand bed from time to time during the day, but lately I’ve been having issues with some of my corals. Because of that, I started checking my tank at night to...

bug in question, image hosting site is postimages since it came up first. this dude showed up on my GSP in a little barnacle/tube worm looking growth on sunday, noticed in the morning when I was switching lights from night to day the polyps on the GSP were all hiding, waited an hour and came...

What worm and starfish are these? Do i add them to the tank?

I dont know if this is a worm or a spider star fish. I have not bought any star fish nor have I added anything to the tank in a very long time! I assumed they are worms but I dont know what type and if they are good or bad

I need help identifying this worm lookin thing. this is the first one of it's colouration and size i've found since i got my live rock over a month ago. based on the fact that i can see bristles on it, I'm assuming it's a type of bristle worm and not a planaria. my issue is trying to figure out...

Hi guys anyone can help to ID this white worm? No idea where it came from. Should I remove it?

Hello, As the image shows. Two little “horns”, they move in an in and out motion, from inside the acro. What do you think? I will try to also upload the video but usually I can’t. Thanks!

Would anyone know what species this worm is? I want to know whether i should kill it or release it back in the ocean. I found it while washing some rocks found on the Jersey Shore. Thanks in advance! :)

I am relatively new to reefkeeping, and I'm trying to identify this worm. I thought it was a normal detritus worm at first, but the antennae are making me think otherwise. Thank you for any help!

I'm trying to get my tank back in order after a bit of neglect after ich got into my tank and wiped it out. I've got the emerald crabs in to clean up the bubble algae, but I have loads of these odd fan worms in the tank and in the AIO sump areas at the back (Chambers 1 & 2), just wondered what...

Doesn’t look like flat worm, I have a couple of these in my pico tank… good or bad guys?

Trying to id this worm good bad?

Today I found this creature at rock gap in my marine tank. This is Worm? Or snail? "Sry for bad video and picture quality"

I ordered some blue hypnea online for my dwarf seahorse tank, they sent two VERY large portions of it. The first bag that I already put in the tank seemed to be clean, but I still rinsed it in fresh saltwater and hopefully there isn’t anything on it. This second bag has hydroids attached to the...

Any idea what this is don't think it's a standard bristle worm. Thick head that looks like a bristle worm that slowly gets thinner and has no bristles. Fell out of a rock during a dip (coral is in qt) I can microscope it if needed

Just saw this fella for the first time today and HELLO it’s long! I thought at first a bristle but it’s pretty flat. Should I be concerned?

Found this thing on a chunk I got recently. I don’t trust my judgement, can anyone tell for sure what this is? I know the picture’s not great, but I don’t want to risk messing with it for a better one :downcast-face-with-sweat:

I think this is a feather duster worm? I have one on my snail too but I haven’t seen the arms come out yet. Am I assuming correct?

Any idea what these guys are? Baby bristle worms?

Hi everyone, I wanted to reach out again because I noticed something on the glass of my tank this morning and I believe I also saw one on the Roch this morning also. I will attach a picture of what looks like some sort of worm if anybody can help me identify this and let me know if it is harmful...

Good day! Please help me identify what kind of worm this is? Is it harmful or useful? How to deal with it? It is green and has a red dot on its back. My aquarium is only 1.5 months old, but there are a lot of these worms. I think they got into my aquarium through the corals.

Help, what is this word I found?

What kind of hitchhiker is this? Swims around by wiggling, its pretty cool ngl
