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...

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...

Bought Marco rock right away I put it in the tank, got 2 coral from Petco: mushroom and Kenya tree after a month in the tank with 3 fishes I ordered more Marco rock to start aquascaping I think is called, break the rock and redesign it, so the new rock came I broke it and since it wasn’t enough...

Over the course of the last couple of days, my spiny box puffer seems to have a worm over his eye. Would a freshwater dip help rid him of it? Any other suggestions as to what to do? The tank is a 220 predator FOWLR. There haven’t been any new additions to the tank for about a month. Water...

Any idea what this thing is? Found this one on the live rock - have also found a couple on the edges of the glass. Its a long white worm that kind of coils itself like this. Originally thought it was the zooanxthellae released by my hammers but after seeing this one changing that assumption...

My tank is fallow right now and with no fish around, I decide to focus more on the tiny things around the tank. I am seeing 3 creatures that I am not sure what they are. Whatever they are they are all over my tank, one grain of sand can have around 6 (yellow line) every spot you see in the sand...

Hello everybody, I just purchased a zoa and upon cleaning it prior to introducing it to my tank I found this critter. Does anyone know what this is? I have more photos and a short video if needed. I am keeping it in a separate container for now. It looks menacing and certainly not shy, makes me...

Found it in my sump on bottom, length is about 1 inch.

I was just cleaning out my filter sock and I found around 4 of these things I don't know what they are, where they are in my tank or how they got in there? But looking at their spikes I might come to an assumption they killed 2 of my fish a lawnmower blenny and a cleaner wrasse. Both of the fish...

I have these strange thin red/pink worms on my glass and they just have appeared from nowhere. I do not have live rock and all of my corals have been dipped. Please help me figure out if these are good or bad. Here’s an image -
