Eliminate the vermocane

How to get rid of vermocane in the aquarium: from traps to information on the sting. Differences between vermocane and eunice.

Thevermocane, also known asdog worm, fire worm or sea worm, should be a welcome guest in themarine aquarium. I say "it should"Because not everyone is happy to host such an animalunclean!

Thevermocaneor vermecane, belongs to the class of Polychaeta and its scientific name isHermodice carunculata. Know that Hermodice carunculata is also present in our Mediterranean and a few years ago there was a real invasion on some of the Sicilian coasts!

Vermocane in the aquarium

Thevermocane in the aquarium, as in nature, it has a length that varies from a few centimeters to 30 centimeters! It lives between rocks and seabed and is considereduseful in the marine aquariumbecause it feeds on decaying substances, dead fish and other debris. In short, a real street cleaner! This detritivore helps you keep the aquarium clean but it is its appearance that condemns it.

It is an annelid, too similar to the worms that make our skin so horrifying, then add that its sting can also be very annoying ... that's why many people wonderhow to get rid of dogworm.

In addition, sometimes the vermocane reproduces very quickly, so much so that in a single rock you can find more than 100 specimens! It is true that vermocans are useful for cleaning the aquarium but ... it is equally true that hosting such dense colonies is not a good experience at all.

Vermocane dangerous for the marine aquarium and for humans?

For the marine aquarium, thevermocaneit becomes dangerous only if it multiplies quickly and its colonies become very numerous. In this case, ivermocanithey can prey on corals, anemones, octocorals, gorgonians, zoanthids ...

Thevermocaneit can also be very annoying for humans as it has stinging quills. We speak of a "vermocane sting" but in reality the vermocane does not have any stings and its "sting" is linked to the presence of those tiny stinging bristles. In case of a sting, the symptoms are redness, skin irritation, itching, in some subjects even swelling, hardening of the skin ... To remove the bristles many recommend using adhesive tape so as torip offaway what remains thickly embedded in the outermost layers of the skin. Other reported symptoms include: dizziness, nausea and vomiting.

From direct experience I can say that the "vermocane sting" is annoying but not so terrifying… but I think a lot depends on the subjective sensitivity and also (if not above all!) On the size of the vermocane in question.

How to eliminate vermocane from the marine aquarium

You can initiate the extermination mechanically, although this will take a lot of effort. Before starting the procedure put on gloves.

How to do?
Extract each rock individually, shake it for a few seconds in sea water (maybe do it in a separate basin and not in the aquarium itself) and start eliminating the worms that come out of this operation.

Check the substrate - sandy, gravelly, even if quartz ... - vermocans can be anywhere. Continue your mechanical elimination.

Every evening, when the aquarium lights are off and the environment is dark, check the seabed and the rocks, you will notice the worms that roam your tank, they come out mainly at night.

This system is very cumbersome but, in the marine aquarium, you cannot introduce poisons or vermifuge substances because you would damage the other benthic organisms in your aquarium.

Dog worm trap

As products cannot be used (so, instead as recommended foreliminate aiptasia from the marine aquarium), the messengers you have available are only mechanics or you can get help from predators. On the market it is possible to find a plastic trap to be placed in the aquarium at night.

Predatory animals

In nature, crabs are the main predators of vermocans but they cannot be introduced into the aquarium! However, you can adopt some stenopus which, with their claws, can be able to capture and feed on even very large worms. Another useful animal is a snail, the Hidatyna, difficult to find and capable of feeding only on small specimens.

Vermocane or eunice

Do not confuse the vermocane (Hermodice carunculata) With the'eunice(worm of rimini or better,eunice aphroditois). The differences between the twomarine aquarium wormsare clear. This is also a polychaete annelid but does not have the typical bristles ofvermocane, has a less flattened body and above all the differences are very clear in the apical area where theeunicehas five antennas. L'euniceit is dangerous for the life of fish and corals, so it must undoubtedly be eliminated.
