In European seas, there exists a relationship between a marine. I bristleworm ( polychaete) and a hermit crab. It is well-known to marine biologists and fishermen.

The sensation has been described as being similar to the average bee sting. There are over different species of fireworms. Aside from the sting, they are as harmless as the common bristleworm. But when hobbyists talk about fireworms, they are referring to one nasty species in particular… The Beared Fireworm or, if you want to get scientific, Hermodice carunculata.

  • Relationship Between Hermit Crabs & Sea Anemones

This fireworm feeds on corral. While this type of fireworm is incredibly rare in hobbyist aquariums, there are still reported cases of it appearing in captivity. This is due to the negative image of fireworms that many hobbyists have, causing them to trap and remove any bristle worm the moment it is discovered. Perhaps a more human touch is needed. Forums like reef2reef and Nano-Reef have a community of enthusiastic reef aquarium owners that can help answer your question.

Checking for bristle worms — how to find them Bristle worms are sneaky little suckers. You could have a whole family of bristle worms hiding in your tank and not even know about it. During the day, bristle worms hide in rock crevices, sand or any other gaps they can squeeze themselves into — the darker the better.

So your best opportunity to spot bristle worms is at night. The problem is, as soon as you turn on the lights, the bristle worms will scurry away into whatever dark corner of your tank they were hiding in. Like many animals, bristleworms cannot see red light and will go about their activities as if the tank is still shrouded in darkness.

The easiest way to make red light is to get your torch and shine it through red cellophane or another red colored plastic. Otherwise there are red flashlight apps that you can download on your phone. With your red light, you will now be able to do some midnight detective work to determine whether or not your tank is home to bristle worms. What do bristle worms do in your tank?

Guernsey marine worms

Bristle worms are bottom feeders — they scavenge for anything that falls to the bottom of your tank. By eating this waste build-up, bristle worms help maintain good water quality. Best of all, they can squeeze into tight cracks to get to their meal. Oh, and they eat fish too. Many people wrongly blame bristle worms for killing their fish. But the bristle worm is just doing what comes naturally, and the fish was likely dead or near dead when the bristle worm stumbled upon it.

The bristle worm is just trying to remove the body before it gunks up your tank. The last benefit of bristle worms is that they can stir up the sand at the bottom of your tank, keeping it aerated. Most people will pay good money to introduce a cleanup crew to their reef tanks while removing another that does the same thing. While they may be creepy, if you can accept bristle worms into your marine ecosystem they can contribute to happy and healthy fish.

So now for the big question: Where do bristle worms come from? Bristle worms appear as if by magic. But the answer to the question is actually very simple: It turns out that you likely put them in there. That last live rock or bag of live sand you purchased? It was like watching a python devour prey. I could see the substrate inside him. I haven't been able to find any information on why a worm would behave this way.

Have you ever seen such behavior? It's about 2 inches deep for what it's worth. Thanks for your time! WetWebMedia has satisfied my curiosity countless times - including today when I discovered I had a few survivors Galaxea of what I thought was a dead coral skeleton! I suspect this gravel "too shall pass". I've since determined that it's a type of Eunicid and he has at least one good-size friend I've also spotted.

The live rock was from Tampa Bay Saltwater and I've heard that they are not uncommon finds in their rock. I believe what I witnessed was the worm building a den as sometimes he just picks up rock and "arranges" it around the entrance, but I'm still puzzled as to why he would swallow it. I'm sure it won't be the last unexplained thing I witness in the tank - may as well sit back and enjoy. Thanks again, and have a great day! Moved a few rocks around tonight and noticed a giant bristle worm pinkish-peach expelling something pink into the water.

Then seconds later another And I have some giant worms Should I be plucking these critters out? No need to remove them. This is a good thing usually. Is it common or well-known for a spaghetti worm to "host" or form some kind of symbiotic relationship with a hermit crab? I have a Mexican red-leg hermit using a Cerith snail shell with a small hole bored in it I assume made by the predator which killed the original snail.

There are two long tentacles coming out of the hole that to me look identical to a spaghetti worm. They wriggle about and withdraw just as you'd expect them to.

Have you seen this before? It's actually pretty common for Hermit crabs to form symbioses of various types with a number of different animals. One of the European species, Pagurus bernhardus, has been quite well studied in this regard.

It routinely forms a symbiosis with sea anemones several species that it actually moves from old shells to new shells as it grows. Inside the shell there is a Polychaete worm, Nereis fucata.

The crab and the anemone are assumed to benefit one another, the anemone by being moved about and perhaps collecting food from the crab, and the crab gets the benefit of the anemone's sting. As for the worm, there's no particular benefit to the crab, but the worm certainly snatches crumbs of food and lives somewhere relatively secure, defended by both the crab and the anemone. As for worms living inside burrows through the shell, the hermit crab likely doesn't notice or care about these, any more than you do the thousands of mites living in your eyebrows.

There's little to no interaction between the two of them, though perhaps the burrowing worms might benefit from crumbs of food that drift about when the hermit crab feeds. Those worms would be in that shell regardless of whether the shell was occupied by a snail, a hermit crab, or was just sitting about on the substrate. It's better to think of a symbiosis as a situation where animals make particular efforts to interact with one another, and when doing so, at least one partner benefits.

Relationship between hermit and spaghetti worm Thanks for the info, Neale!! I think it's kinda funny, this crab is hauling around a freeloader! On top of that, there are mites in your eyebrows, amoebas crawling around inside your mouth, yeasts on your skin, and more besides!

Bristle Worms: The Creepy Creature Hiding In Your Aquarium

The only thing unusual about the "freeloader" you're seeing on your Hermit is that it's visible; most aren't. Do you think he's dead, or is this normal? This is sometimes "normal" If the worm is healthy, it will regrow its crown. I am enormously thankful for the information here, read daily, and want to kick those who are intentionally ungrateful or rude to the staff of volunteers there.

Thank you so much for your site, I have successfully stocked 3 tanks lightly with sick or dying corals from others, and all have regrown beautifully.

Tank houses much live rock, Chaeto, a small Tomini tang, algae blenny, and a falco Hawkfish, as well as a 'non aggressive' clean up crew. I change five to ten gallons with aged water twice a week [RODI], use an Aquaclear for Polyfilter and ChemiPure, as well as a cheap skimmer modified which pulls an enormous amount of disgustingness out of our well fed water.

Flow is provided by two Koralia 2s and an intermittent Koralia 3, and the lighting is power compact [ watts]. I do not have a refugium or sump connected to this tank. He has been in the tank for more than eighteen months, and has grown and behaved like your average feather duster in a fabulous environment with plenty of food.

However, his morning it was extended out of its tube by three inches. Within an hour or two, he crawled out, and to my surprise, appeared to be cut in half about three inches below the crown. The two ends of the 'cut' appeared relatively clean, but with one small piece of flesh holding them together. So, now I have a feather duster tube, with the lower end of the worm in it, and a free floating and protected, for now top half of a feather duster in my tank.

I am inclined to remove the upper portion, but would hate to do so if it has even a slight chance. They sometimes do this. Just let it be. I changed 15 gallons anyway, and everyone else in the tank appears to be happy and healthy. I have no idea how this could have happened, and while I have a few tiny hermits, as well as the normal population of bristle worms- I do not see how anything in my tank could have mechanically injured the feather duster.

The worm might have done this to itself. But I couldn't tell you what that irritate might be.

While I queried this, I myself have never seen a large feather duster snip itself in two. Any advice or thoughts would be much appreciated! Thanks you so much. Feather duster cut in half?

I suspected that I should leave him be, but I was too caught up in freaking out. It might likely be rebuilding its tube as we speak. I was scraping my tank walls and creating quite the amount of wave action. Water started changing into milky colour, very quickly. Bottom - No sand - shells only and rocks.

Fishes were bothered a little by the whole situation; corals and anemones not at all. During the day, when I vacuum tank's bottom, always get a good bunch of them. If that what happened is what I think it is - I'm in trouble: One good thinks - they have to eat what is left on the bottom after snails, crabs and shrimps.

After few hours water is still white cloudy. What in the world what that? Night of the Triffids? I wouldn't have recommended anything smaller than a g to start - for the shark alone! Am concerned though, about its well being in a crowded community tank. Sharks, especially just out of the case, are vulnerable and in need of some quiet and care.

I managed to film one of them doing this. By the way, thank you for sharing this experience with us. It helps us all! The entire tank became as cloudy for a bit. Now, my questions are 1 What were they doing? Please see this link regarding nutrient control: It's also not an ideal situation for the inhabitants.

Please read these links for more information on shark keeping and compatibility: It did this for several weeks then sort of settled into the pink color until it shed it's "heads".

After it grew a new pair of heads, the color switching began again and is still changing colors now. It is getting close to full size again so I don't know what's next!

We also have video documenting color change in real time. Don't know if we have the only one or they are common but I've never seen anything quite like it. At first I couldn't see anything in his claws but he seemed to be wrestling with something. A moment later two thin strips of vivid electric blue lit up between his outstretched claws and he jumped back like he'd put a pincer in the mains socket.

Eventually I could see he'd caught what looked like a 2. It was too dark to make out properly, and I didn't want to suddenly light the whole tank up, but the worm looked thin and flat, and while the boxer tried to eat it the worm shot lines of really bright electric blue along its body. The glow clearly hurt the shrimp, though he didn't give up, and at this moment the boxer appears to have won and is slowly eating the worm.

Now that the glowing has stopped the worm looks very plain and could easily be a bristle worm, but do they glow like that? I almost wanted to stop the boxer killing it but short of pulling every rock out there was no way I'd separate them, and I also wondered if this worm could be a danger to the fish anyway.

I'm a big fan of Wet Web Media and have spent many hours reading through your FAQ's, so when I saw this unexpected and unidentified creature I thought of contacting you first. Have you any idea what it was? I'd love to know your thoughts. I've tried looking for similar things online but turned up no clues at all. Thanks in advance for your time, and thanks for the great site.

Electric worm in my reef tank! I feel very privileged to have seen this if it is not commonly observed in captivity. Now I'm trying to find out what the tiny star shaped white things are on my glass, they look sort of like tiny white starfish in shape only but with only 4 stubby 'legs' Any ideas would be very welcome I'll continue my search on that.
