worm id

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

Found a red slimy worm that has stringy extensions could be a spaghetti worm but never seen one red. Sifted through the sand to see if there was more and didn’t see any so far. This one found going after my torch.

Found this worm looking thing on the glass? Looks like it survived a dip at some point, very dead now but thinking where is the other 100? Thanks!

Just noticed this and I think he has a little friend. Is this the start of aiptasia or is like a feather duster?

Hey guys, thanks in advance for any help. I’m hoping for some help IDing a wormlike hitch hiker based on description alone. I apologize I did not manage to get a photo of this thing as it only seemed to come out after lights off and it was super thin, the camera would not focus. I will try to...

Hello Everyone, So I am currently concerned but not too concerned about these weird pests that I have found living on my Zoa Coral. I am not sure exactly what they are but I would like to figure that out sooner then later. This way I can take care of it if needed. So far from what I have...

Hello, I recently started noticing 2 small white centipede like “bugs” on the glass of my tank. They have antennaes, many “feet” like a centipede, move slowly, and are completely white. The bugs are very small but still bigger than pods. My tank has been fallow for 8 weeks now following a...

Any ideas what this is. It doesn’t move and I can’t scrape it off. Just got him from the store
