If the poison from FW's can kill Bristle worms think what it is doing to everything else. I will probably move the few things I have left to a 29 gal. Hermit crab using a littered plastic pipe for a home.. Really .. Bristleworm: Bristle worms are free-living segmented worms with an elongated body which bear. symbiosis. to practice, you can use the "test" feature, select "multiple choice" and "start The bristle worm removing parasites from the hermit crab and eating the.

I say, "only on live starfish," as they will not take dead or frozen ones. You'll need a fresh live starfish, preferably the genus Linckia Blue Starsand they tend to consume one every four to six weeks.

Seeing a starfish torn apart and almost completely eaten may not be the thing you want to witness in your home aquarium! Besides being carnivorous, they are very territorial. Therefore only one or a mated pair can be kept in the same aquarium. There is some thought there may be another similar species H. A very small 2 cm shrimp with a translucent body with white spots and flecks. Tips of its claws and the telson have bluish purple bands.

FAQs about Arrow Crabs

Lives in a symbiotic association with various anemones and also some long tentacle corals, e. In aquaria, needs a host anemone or coral.

Depends upon the cleaning process for its food. Difficult to maintain in the aquarium, especially if there are large fish. Will have to leave the anemone when it molts, therefore can easily be eaten by larger fishes.

Family Rhynchocinetidae Rhynchocinetes durbanensis Even though the genus Rhynchocinetes contains a number of different species, R. It has a pale red body with numerous white lines and spots and reaches about 2 inches 5 cm. Hides mostly by day, usually on the underside of elevated rock.

It comes out at night to feed and has a taste for zoanthids and flower coral, and will occasionally pester or pinch other soft and stony coral. This may simply be in search of food or the cleaning of certain pests from corals, but be forewarned, usually not acceptable for the reef aquarium. Should be maintained in small groups of five to ten, where the males will set up small harems.

Difficult to feed because of its shyness. Sinking shrimp tablets make a good foodstuff. Similar in appearance to R.

Bristle worm trap homemade, how to remove an eliminate

It hails from all tropical seas and is found in coral reef environments and generally wherever there are caves and holes. Its one of the favorites among aquarists and are easily kept in the reef aquarium when there is sufficient hiding places.

But it can do harm to corals and anemones when there is insufficient food. It attains a maximum size of 4 inches 10 cm and is equipped with three pair of walking legs, with two very strong pincers.

They will also set up cleaning stations, but seem to be infrequent cleaners in the aquarium and should be maintained singly or in mated pairs. The female has a heavier body, carries her eggs for about two weeks under her shell. The eggs can usually be seen through the shell where they are first a yellow color, then turn a light green. When the female molts, about every 16 days, the eggs are fertilized by the male.

The eggs are hatched in the female's mouth in small numbers about two weeks later and released into the water column. The baby shrimp are half the size of newly hatched brine shrimp and can live on their yolk sac for three days. Rotifers are a good food supply until the babies can take larger food.

Adults accept defrosted pieces of clam, shrimp, krill, fresh fish flesh, or live brine shrimp. Technically, it's considered more a lobster-like creature than a shrimp. Mantis Shrimp The Order Stomatopoda contains one of the most dreaded shrimp in any aquarium that contains fish or invertebrate. Generally, they show up as hitchhikers hidden in holes inside live rock. Some can get quite large, and have personally seen specimens that appeared to be about 10 inches 25 cm in Mexico waters. They look quite similar to their terrestrial counterpart the "Praying Mantis" hence their name.

These are awesome predators, and are armed with powerful appendages that can destroy hard-shelled prey. Pistol Shrimp make a sound similar to a single 22 caliber shot, however, mantis shrimp also make a noise, yet theirs is more like a machine gun, i. It a good way to tell whether it's a mantis or pistol shrimp!

If the rock its living in can be removed from the aquarium, submerge it in a pail of club soda, and the shrimp will quickly leave its hole as it can no longer breathe since the club soda is nothing but water and dissolved carbon dioxide. If the rock can not be removed, plug its hole with another small stone, or fill the hole with the same type of glue that is used for cementing coral frags.

Family Odontodactylidae Odontodactylus scyllarus This one species, Odontodactylus scyllarus, is purposely collected for the trade, as its name is a good indication of its colors. It hails from the Eastern Pacific and is usually found on rubble covered bottom areas and grows to 12 inches 30 cm. If maintained by itself in a small 20 to 30 gallon aquarium with sufficient bottom sand and live rock for hiding places, it makes for an extremely interesting display.

Requires daily feedings with meaty foodstuffs. 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! 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.

The 'LIVING' Marine Aquarium Manual

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. It's great to have WWM as a resource to help identify them, and to have your personal replies is just fantastic.

Thanks again for your time. I drip-acclimated him like I do everything, then put him in a crevice where the bottom of the tube would be in the substrate.

I never once saw him come out of his tube. I didn't actually watch the guy at the LFS bag him, but I left the tube in my tank just to be sure in case he was still in there. Once the lights went on, it started pulsating and eventually disappeared.

The tank is about a month old and everything in it either came out of my gallon tank or I bought as a frag. Is that thing my feather duster? If that is him, will he decide tube-life is not for him and make his new home in my live rock?

What a planet eh? My question has to do with what I believe is a spaghetti worm. It never shows itself, and never changes position, but it sends out about 8 long, white tentacles, about inches long. My problem is that every so often, it emits a dense cloud of what looks to be organic material that eventually clouds my tank.

Is that stuff harmful?

Or could it be beneficial? My tank is 50 gal, with about 35 lb. I have tried to find out on your site and in my books about what happened in my tank 2 nights ago; if you can direct me, I would appreciate it! I am really new at this, but I Love it!
