Is this something?

[Streetlamp]

I'm pretty sure this is new, I noticed it about a week ago. Its about 3-4mm high with a round base.

Possible vermeted snail(spelling) or it's just a feather duster does it through out a spider wed looking mucus when you feed?

 

[Streetlamp]

Not sure on the mucus i'll have a look.

 

[BeardedMcG]

Agree on the vermetid snail.

 

[DEWreefing]

Snap the tube off the squeeze super glue gel over the whole round part

If you don't see any mucus webbing then it's a harmless calcerous polychaete which is commonly mistaken for vermetid worms.

 

[sullyman]

they are all over the rocks, start breaking those round tubes

 

[Streetlamp]

@DSC reef there's no mucus from it or anything in the tank

@sullyman If they're all worms I'm in big trouble as I'll never get them all, they've been on the rock since day one and as above I've never seen an mucus coming from anything. I think with that many I'd definitely see lots.

Do you ever broadcast feed or stir up the sand bed at all when doing a water change? If so the vermited snails will cast a “web” to collect the detritus in the water column.

 

[Streetlamp]

Yep I broadcast feed and there's no web's. I'm not going to panic and just keep an eye on things.

I don't think they are vermetid in that case.

+1 not verms.

 

[sullyman]

were the tubes on the rock when you started the tank? Or have they been developing along with your tank? they're a lot of tube worms, I know the red ones sting. could be a different member of the family. Can you see worms in all those tubes? If so I'd
do some offensive defense and start a carpet bombing campaign. Do you have a wrasse, if so break tubes open and let the wrasse eat away. They can take over a tank before you know it. The ones that don't shoot out a mucus still sting things that get too close

Update: Over the weekend the offfending item got smashed up. During feeding i thought I saw a tiny sliver of webbing, then I saw food being pulled to wards it. I'll keep observing the other things but I'm not too concerned by them.

Look up digitate hydroids as well, they have a tentacle that can pull food in.

Are we talking about the round white things now that are at the 10 o'clock position from the green circle in the original post?

If so there's no sign of life from these, and I believe they've been there since day 1. There looks to be plenty of old dead stuff on my live rock. I'll try get examples later.

No, digitate hydroids can look like a web but are completely different. Here is a picture of one for reference

Ok Thanks, as we stand now we have no webs. We won't panic about anything for the moment.

While we're here, what are the white things I've seen them on other rocks posted across the forum.
