worm id

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...

Hello everyone! Recently was able to get some sand off the Florida coast and was planning on putting it in my current seed tank. I was wondering if these free floating worms were detritus worms? They’re not too quick and are attracted to light. Thanks!

What is this infestation? It’s contained in my sump and especially my refugium for now, but I’m afraid my display is next. I assumed flatworms, but they just look a bit different than the pics I saw online. They are also fairly firm/hard and do not squirm or move when touched. ID anyone? Good...

I have no clue. I just treated (twice) for flatworms using flatworm exit. This is long and moves fast. Doesn’t have the shape of the brown flatworms I eliminated

This guy crawled out my torch coral during a dip. Not sure what he is. Checked the guide and its not on there. Taken Coral RX 30 mins to kill it.

Last night i had a quick look round the tank with a torch and out of nowhere this 1 inch, thin, very wiggly worm followed the light. Because im having a nightmare with dinos, and torch coral mites my patience is waring thin with problems so i led it to the bottom edge and killed it with my...

Hello everyone, I recently purchased some live rock from kp-aquatics and am having some trouble identifying two hitchikers. One is an isopod that I think is Sphaeromatids but would like to get some other opinions. The third picture is the isopod curled up on its back. The other is a worm...

Apologies for the horrible picture and under blue lights. But any idea is this is a fireworm or any harmless bristleworm?

Hey everyone, I noticed something weird on my rocks and was wondering if someone can ID it for me? I’ve looked around online with no luck. I’ve had the tank for about a year and this is the first time I’ve noticed this. Thanks In advance!!

I have been setting up a small NPS tank with my Fluval Evo 13.5 and recently noticed a small red object in the sand bed. At first I thought it was just a left over piece of Gracillaria or something but I took a closer look earlier because I noticed it had moved and realized it has lots of little...

is this worm good or bad? I dip all my corals yet here he is

Hey everybody I was hoping for some help in identifying these worms in my tank. If anyone could help I would greatly appreciate it! This is the best picture I could get. The worm seems to have a white dot near its neck and a white dot on its tail.

It’s late at night and I was observing the night life on the reef, and all of a sudden this red like worm came swimming up to my light. I’ve never seen this particular creature before but it resembles a bristle worm but I’ve never seen them swim, and holy cow does this thing swim fast. Also has...

Hello good people of R2R, I have what I think is a Eunice worm in my tank but would love to hear that I am wrong. It decided to come out with the lights on today and I was able to get a decent look at it, and even snap some terrible photos- it is VERY sensitive to movement so unfortunately these...

My Fire Shrimp had a normal molt and for fun I looked at the old exoskeleton under my microscope. Is there a way to find out what sort of things live on a shrimp normally? Or if some of these little guys just live in the saltwater in general? Interested if anyone has good resources or knowledge...

I've noticed there are a lot of posts about worms already but I don't have time to check each one. So sorry but here's another one! Backstory: Bought a bunch of macroalgae from Gulf Coast Ecosystems and noticed a weird worm still alive between a bunch of branching Coralline algae. When I poke...

Had these guys start to takeover my tank anyone know what they are? They are about 2 inches and extend and retract their body to eat and have very small hairs on them like a bristle worm.

I’ve never seen any bristle worms this hairy? Any ideas??? Thanks, Joe
