- Thread starter Rini
- Start date
I looked at the top one today and it does exactly the same thing what rini has filmed. It has a small net now. I tried to film it but i pissed off the fish (been there for a day so i stopped trying to film it) but we have the same type of worm thats for sure.

Are you sure it doesn't have a trap door that closes off its tube? I'm really leaning towards something that is related to vermetid snails with these that you have. Not the standard ones you generally see in tanks, but something similar.
Check out the video on vermetids website: http://www.realmonstrosities.com/2013/09/worm-snail.html

Finally a picture from the front. It looks like this day and night not really a trap door. Haven't seen it closed. This is the top one. The other one growing like hell. It does retract but not really shutting "the door"
This weekend i will try the link and see if i can come up with something.

@relexus That is the pic I needed. Okay, it is a mollusk (snail), not a polychaete (worm). I'm almost 100% that it is in the Vermetidae family. But, it isn't the type that most people on this forum have posted about. The structure of the tube is different and it doesn't close itself off with a operculum (trap-door). It is not always possible to ID down to the species level. And there are always new species being discovered in the oceans.
Here is more info on them: http://eol.org/pages/2527/details and http://eol.org/pages/2527/media
It seems that there has been much controversy over classification of these as there is a great amount of difference with the species. Some vermetids are solitary, whereas others live in colonies, partially cemented together. The shells of species within this family vary greatly and can sometimes be extremely challenging to identify. Some species have an operculum and some do not.
The closest I could find is this one from Moorea: http://eol.org/data_objects/15599822 a Serpulorbis Variabilis (Genus Serpulorbis). And these in Hawaii: http://www.marinelifephotography.com/marine/mollusks/gastropods/vermetids/serpulorbis-variabilis.htm. Brown shell crossed by strong spirals & ribs. Animal color variable, the only Hawaiian species lacking an operculum. Aperture diameter of 1/3 inch, length of 2 inches.
Here are some images you can compare to:
