Weird Worm Thing?

Hey guys,

so for the past two months or so I've taken note of this creature in my tank that is unfamiliar to me.

Its hard to explain but basically a tube has slowly been growing in my tank off of a rock. Its probably 2 inches in length at least on the exterior of the rock and who knows how much deeper into the rock. Its now half covered in coralline algae though. Within this tube, which has the diameter of the smiley faces when I post, so about this big

, is a worm of some sort.

It barely sticks out, if at all. It has two antennae and out of its mouth it creates a type of web almost. Sometimes it will shoot almost like one strand across to another rock and other times there'll be a lot of this web swaying in the wind just below, as if it didnt attach across the way.

Im not sure if its using the web to filter feed or what, but its a weird creature and its tube grows a mm every week probably.

Anyone encounter anything like this and knows what it is?

Ok after watching it for a while, it definitely casts its web or net our to the adjacent rock that is about 3-4 inches away and then collects debris in the water for 5 minutes or so and then reels the whole web back in. It then occasionally will shoot out a puff of "smoke" or sediment I suppose after eating the food.

Obviously the worm is a filter feeder but Im just interested in it. Anyone know what it is?

Vermatid Snail.

Actually abit of a pest as it will cast it's web out across corals and such.

Ive notice this in my tank too! The web can get pretty big too! How do you rid this guy?

Use marine putty and plug the end. Once it goes hard the snail is stuck; unless it finds another way out; which hasn't happened yet!

Works for me.

haha too bad! Hes pretty cool. Im gonna leave him for a bit until he causes problems since I like him. I dont have enough corals near him yet for him to be a problem.

Hi,

That would be a vermetid snail.

Can be a real pest when they multiply and the mucous net can annoy some corals.

I normally plug the end with putty.

Hope this helps.

Simon.
