worm id

Appreciate any help ID this stuff on this new frogspawn frag I got today. What is red spikey stuff? What type of flatworm? What could this tiny red worm be? Thanks so much!

Hello, today i found these red worms. I couldn't get a better picture because they are tiny. They have a distinct red color and were moving like a worm. Does anyone have any idea what they are? Thank you!

Anyone know what that is as in the video? Found it after lights are off. Before the video. I saw it swimming frantically.

Noticed this today. Any idea if this is a tube worm and if I should worry or not. Also what should I do if I should worry lol

I just saw a relatively big worm come out from my rock and grab the leftover brine shrimp and then back out to the rock… should I be worried? What is this?

I have never had a bristle worm and really don't like them! Can anyone give me some more information on this one?

Hey everyone, Pretty sure a Feather Duster caught a ride in my Goni, but is it harming by setting up camp inside the Goni skeleton? Here are videos from a week ago with the gonis extended but now the Goni hasn't come out like it used to. the FD sticks out of the dead (darker) part of the...

I found this worm in my live rock, it is not a bristle worm.. They are fast and leave a slimy string, I catch this one in diy trap

this zoa has been in my tank one week or so and this worm thing started popping out of it today. Any clue what it is? Should I pull it out?

Second worm I saw like this. Looks almost like a bristle worm but it’s not a bristle worm. Anyone know what it is? I attached the video link below.

Hello, I have this very long gray worm that came with my live ocean rock. It looks smooth and I can't find anything that looks like it online. I’ve seen it on top of the sand but it’s currently underneath. Can anyone id it?

I have these “worms” in a few spots in my 55 gal reef not sure what they are or if they are a pest or not.

I've tried to ID these guys, but I swear they look like 10 different worms when I tried comparing pictures. This is through one of those phone connected microscopes, as the worms were crawling through the sand. They're about 0.5in long, super thin, and white to the naked eye.

Is this a fancy worm or a brittle star? I see something that looks like tube feet, so maybe a star? I do not know where i got it from, i saw no stars in chaeto, this piece of rock(the only live rock i bought) or on the small rock with zoas that was gifted to me. Will it divide into more specimens?

cool video of my 1.5 year old mandarin eating some kind of worm from the rocks … what do you think it is ?

Hi, hope you all are having a nice day! I was doing my weekly maintenance on my tank and realized that there are a ton of these little worms in my tank, will attach video of them and photos. Not sure if it's normal or do I get rid of them. Appreciate your help!

Just saw this today and was wondering if anybody had an idea of what it was.

Good morning all! Rearranging a Zoa colony found this guy. Is it around 2” long. Quite cute the wanker. Is it friend or foe?

So i noticed this weird tenticle pop out of one of my rocks. Kinda looks like a bristke worm but its huge. This is the best video I could get.

Hello Reefers, I’ve noticed these red / orange worms in my tank. Seem to have hair or bristles. Can anyone identify? Good or bad? Thanks in advance.

Been trying to ID this worm on the side of a rescue coral. It is a hard shell with the mouth on the left side. I think the coral is a torch, but still recovering. The coral has white milky stuff coming off every few days.

I was watching my rock flower nems (because I keep hoping for spawning) and saw this thing, i thought it was one of my brittle starfish at first, but you can see one of the starfish legs above it so I know it's not that. Plus it moved like a worm? And like folded into itself, also it almost...

I seen these critters as I was cleaning out one of my chambers. Its was in a green ball of algae.. I don’t know if it’s a bristle worm.. I also think I’ve see these little wiggle monsters under a microscope a few weeks back but just seeing them with my own eye freaked me out. Anyone have an idea...

Hey guys So we are a good few weeks into the 20 gallon and I have 6kg of live rock tank mates are Nasarrius snail, 2 red legged hermits and a turbo snail who is doing a great job on the algae clean up. The rock is covered in copepods but I noticed a weird tentacle earlier! There was a small...

I’ve been trying to figure out why this coral is dying and the rest of my tank is fine. I’m thinking it has to be a pest or something. I just noticed this fuzzy worm playing peek-a-boo. It has a fuzzy looking body with a more compact “head”. These are the best pictures I could get. I figured...
