Mini tube worms

[kuay5]

I have alot of these in my tank.. mini tube worms that builds a hard calcium tube.

Are they harmful or what effects do they bring to the tank? reduce calcium?

For me i have to take out my PH probe every few weeks to clean and soak in vinegar to remove them as they grow eveywhere, including in wavemakers..

Many hobbyist desire such tube worms. regular water changes will alley your calcium depletion fears.

They can sometimes be a little annoying. Covering equipment and restricting flow is the worst...

Are these the ones where they have small fillers and spit out like spider web? I think i have some in my tank... irritating and make the tank looks dirty.

hi CFOh, could be Vermetid worm, it looks a bit like this.

Seems like its fairly harmless so long as not encrusted to wakemakers/pumps etc.

Talking about vermetid worm, it seems like they are also thriving in my tank. Recently noticed quite a few of them appearing. There's also a very large one. I hope they are eating the detritus though..

Interesting fact: Vermetids are actually snails, not worms. http://reefkeeping.c...01/rs/index.php

I'm assuming Kuay5 is talking about mini feather dusters as shown below:

Another similar looking creature is the spaghetti worm This do not produce calcerous shells.

most reefers consider the first as pests and the other 2 harmless. I think they are all harmless and help clean up your tank of leftover food.
