worm id

I got these pipes on my coral looking like a vein. It just came about 1 week ago on it. Will it harm it and how can i get rid of it? By movement or light, it pulls inside. First pic its out nd 2nd pic its hiding inside. thanks!

Just saw this floating around in the bottom of my bare bottom tank. Took it out for some inspection. Included pictures of what I would along with the rock if that would help identification. Thanks!

Hi! I noticed a nasty lil worm thing moving, inching its way out of a hole in the rock. Obviously I was curious to see what the heck it was so I turned the tank light on and it shrunk back in the hole. I'm new to saltwater tank keeping so I just want to make sure this isn't a harmful parasite of...

Cleaned out my HOB filter today and found this guy on the filter. Never seen anything like it before. Currently the tank has a six line wrasse, a diamond goby, and a couple hermit crabs. Tank is 29g also, any idea of what it could be?

My tank was taken down by a parasite, and after losing all my fish, I let it sit for a few months. No, I’m looking to get back in. I need to do some major maintenance. As I am beginning to clean and replace the water, I’ve noticed my tank is now infested with some strange worms. Should I...

Any idea what this little worm thingy is?

Hey guys! My friend found this weird critter in their tank and we have no idea what to ID it as. Looks like some type of worm. Unfortunately there’s no pics of it in the water but I’ll attach a couple of pictures from outside of the tank. The spikes along it move almost like an urchins spikes.

Hey guys anyone have any clue what this could be on my puffer? I treated the tank with parasite meds but I’m a beginner and I don’t know what’s going on I want to help him I have no clue how to please if anyone has any suggestions it’s getting darker and has been about 2 weeks since I noticed it

I found this worm in my tank today. Maybe 3-4inches long depending on how it's stretched out. Very skinny, and white with long hairs coming off the sides. The hairs are longer and further apartment than say a bristle, or fire worm. I've tried to identify it, but haven't been able to. Just...

I found this worm in my tank a week or so ago. I decided to pull it out tonight to get a better look at it. I don’t think it’s a bristle worm. I’m worried it may be a bobbit worm of some sort. Can someone ID? And tell if it’s dangerous or not. Thanks.

I was rearranging my scape and took two large pieces of live rock out overnight. This giant worm was on the floor, still moving so I put it in water. Bobbit worm, correct? I had 3-5 fairy wrasses disappear in the last year and a half. Most recently a Naoko. All new additions so I assumed...

I have this Worm isolated, not sure if this is a good or bad guy for my tank !! any ideas? thanks!!

Hi, I have two different subjects that need ID-ing. First, I've been battling Amphidinium Dinoflagellates and have been dosing Silica (Brightwell's SpongExcel) to encourage diatoms. Here's the first shot. Looks to me like possibly pennate diatom. Thoughts? Second, Just recently dipped a...

what are these little brown like clear worms? and are they good or bad? Sorry can’t really get good pictures they are tiny.

Hi, I’m trying to identify a tiny worm. I added some live copepods and 1hour later my tank is covered in thousands of these tiny white worms. I’ve tried to get some good microscope pictures so maybe you could help me! Thanks!

Saw these small white worms in the live rock I purchased. This is my first tank, the rock was not dipped after picking it up from my LFS. Just wondering if this is a pest or something that is not harmful. There are no fish or coral in the tank and has been cycling for 3 days now. Should I be...

Hello, I need help on an Id of this critter. at first it looked like a nudibranch when I saw it posted up on top of my rockwork. after fishing it out of the tank I can now tell that it has a bunch of long streamers coming off of it. Sorry about the doo doo iPhone pictures.

I just added 2 banggai cardinal, a YWG, a green mandarin goby, a blue hippo tang, and a flame angelfish from DR Reef's quarantine fish to my 200 gallon reefer xl Unfortunately the flame angel, one cardinal, and the YWG all died within 3 days. Water parameters are normal and the other fish are...

Hi All, I am hoping someone can ID this guy. It came off an elegance coral that was in QT. This was the coral's second dip, so I am assuming that there was an egg that I missed when cleaning it the first time. Any help would be appreciated. Thanks

Found these worms in high concentrations in my coral tanks - not sure what they could be and need an ID! Thanks! Not sure if it’s a type of flatworm? Finding them on tank sides and other surfaces but they don’t seem to be on the corals. They move quickly as well - hopefully the attached video...
