bristle worm

I’m still learning this hobby, and I’m like 99.9% sure this is a common bristleworm. However, figured I’d make sure. this guy is harmless right? Any benefit to leaving him in the tank (I’m sure this will raise some sort of debate). thanks!

Can anyone confirm this is a nudibranch and bristleworm? Released during dipping of some frags.

Hello All, I've had a red, brittle starfish for a few months and recently saw about 10 miniature (Image 2 is one of the 10 starfish), clear brittle starfish emerge from a hole in my live rock under a hammer coral, ranging in size of 2-5 mm diameter. These little guys have been hanging in there...

Hey! Just found this guy in some red oga macro algae I bought today fire worm?? Bristle? I like bristle worms

GOOD GUY OR BAD?: Here is a pic. Is this a fireworm or a normal bristle worm Thanks - The Fish Tank Hobbyist!

Good day all, my assumption this is a baby bristle worm but would like a confirmation or a different opinion. Mainly hoping it’s not a B-Word worm! Lol! Thanks in advance!

Hi Guys, I bought a new hammer coral about two weeks ago and today I noticed a possible hitchhiker on the back. I dipped the coral in Coral RX Pro and Seachem Reef Dip when I got them. It seems to protrude and then goes back in if one of my hermits passes near. I’ve tried to take some pictures...

Wondering if this is a bristle worm.. I know I have some in here but this this is super fast and doesn’t seem like it is one, and if it is not a good one. Also, ignore the golden girls commentary in the background

I Found this little creeper in my filter. Is this a harmless bristle worm or should it be voted off the reef? thoughts on ID? Thanks all!

Hi all, my first post here so bear with me. relatively recently have had a 37 gallon going for about 2 months. I started with some great live rock but discovered what I think is a bristle worm. wondering if i should let him stay or remove immediately. He comes out during feeding time between...

I think I have a bristle worm in my live rocks, but I don’t know if it’s a fire worm or if I should leave it in the tank. I also have what looks like a peanut worm, and the fish at the end of that video can someone help identify it? I think it is a juvenile zebra blenny. Rocks came from Hawaii.

I’ve seen some normal looking bristle worms in my aquarium but nothing like this almost hot pink looking one. Fireworm perhaps? How should I go about removal or is that even necessary? And sorry about pic quality i hope that doesn’t affect the ability to identify it.

So I bought a used biocube 32. I haven’t got any livestock or coral yet but I plan on a seahorse tank so anything that stings is a no no. As soon as I set it up I started seeing small bristleworms, too many to kill by hand. Now I’ve seen a really big one, and I’m wondering if there are any...

I have seen like 7 of these worms in the last hour and i think they are bristle worms, sorry for the bad pics

Hello everyone. A few days ago I was feeding my candy cane coral (a very small head) when a worm came out the rock and snatched a piece of food. I didn’t get a good look at the worm and it pulled the food back into a hole very, very fast. On previous days I have seen a small clear worm, very...

I have a 16 gallon bio cube with no fish or coral right now. It’s been running for about 8 months. I’ve noticed tons of what look to be bristle worms and lots of other little bugs running around the sand bed. Want to be sure what they are so I can remove them. Couldn’t get great pictures though.

I was doing a water change this morning on my tank and afterwards I saw this huge thing come out of the rock that have never seen before. And it didn't look like a bristle worm that I've seen on the internet before. This thing is pretty huge though. Thank you in advance for any input! :-)

Big worm- little fish Long story short I finally caught a bristleworm that was living in my pico reef. Its BIG about 2-3 inches maybe and fat. I have a frag tank with a six line in it, still pretty small. I know people use wrasse as a pest control for these guys. But I'm wondering if a six line...

I'm setting up a sexy shrimp and rock flower tank. A waterbox 4g. I've had it running a couple months with only a few rock flower nems. Recently bought gsp from a local reefer, and noticed a rather large (2+inches) bristle worm try to steal food from a nem during the last feeding. I presume he...

Hi, I am new to the hobby and have just begun cyclying my first reef tank. I have placed 5kg of live rock in my 24L (6g) tank and with 3-4 days it began to small bad. Since then i have done a 40% waterchange, and it only seems to be getting worse, there has been a plethora of worms (majority...

So I previously had a problem with two bristle worms/fireworm (never figured it out 100%). Ended up catching one and never finding the other (may have died). Now I went down to check on my tank and saw these two little white lines thrashing around at the top of my tank, I turn on my white...

i got a small maxima clam for my 33g last Thursday and it seems perfectly healthy however in the mornings and at night I’ve seen a total of 4 on it and 1 several weeks before I had it, I’ve killed all the ones I’ve seen on the clam but couldn’t find the bigger one again, does anyone know if they...

So I recently added a Maximus clam to my 30g reef tank and it is adapting great but every night and sometimes in the mornings it will have a bristle worm or two on the shell, I've been removing them with tweezers but I know that this is not sustainable. I always wanted to get a clam so removing...

Couple of questions please...woke up to find 3 of these bristle ? worms cruising around my unlit tank. I'd just like to say I MAY NEVER STICK MY HAND IN MY TANK AGAIN. 2 of the worms looked like greyish-tannish nondescript bristle worms but this one looked different...is it a fire worm...

So my Falco Hawkfish exterminated all my bristle worms within a week. 3 months later and I kinda miss those little guys.
