What are these Cobwebs?

[keddre]

Anyone have an idea of what these Cobwebs are, or what's leaving them?

Mucus nets from vermetid snails

 

[keddre]

Mucus nets from worms

What kind of worms? The only one I'm aware of, is the lone peanut worm in my sump

 

[Hamm Corals]

Yup vermetid snails

yeah I meant vermetids. snails, not worms

 

[keddre]

In sitting here reading about those snails, and if that's what they are then it would make sense as it's a filter feeder tank. My only worry is how course they are to my gorgonian. Thanks

Definitely Vermetid. I have two that live on one of my Trochus snails. I've been told they can be invasive, but in two years I have yet to see another in my tank. It's kinda cool to watch them "fish" with their silk.

 

[samnaz]

A year ago I only had one, now I have hundreds. Wish I could go back a remove them before they took over, but now it would be impossible. Their nets steal food from my corals and shrimp, there is just no stopping them.

 

[saltyfilmfolks]

They don't sting all corals strangely. I let a big one get big just to see what happened. Keep an eye on it. And yea, another challenge if filter feeder tanks.

I kinda think my Pygmy angle is taking care of them when they are small. I should have them and aptasia too running amok.

I had some in my nano. I clipped them off the rock and got rid of them. They were getting their webs all in my frags, ticking off the PE... It's been a few months and I haven't seen one back yet.

 

[Somuchflo99]

Vermitide snails for sure had the same problem

 

[keddre]

Welp, just because I need the food going to my gorgonian and not these snails, I'll clip them as I find them. I only see these webs one every month or so, so it'll probably be a while until I can find them. Thanks everyone

Every month or so? Vermatid should be almost every day. Sometimes all day.

No signs of where the come from?

I couldn't find the source the day I posted this. I should preface this by saying that I usually don't see my tank until noon or later, so if they are throwing their nets, they have 4/5 hours of lights on to hide

 

[samnaz]

Mine only throw their nets when I feed the tank or stir up the sand bed or baste the rocks.

 

[matsrosenberg]

I've seen something similar happening when overdosing vinegar in my kalkwasser or overdosing alcohol. Killed all my snails so now I know what to be extra careful with... .

I haven't find a link between when mine throw them. Just kind of happens

Lol, I don't dose anything, minus some phyto and zooplankton

 

[saltyfilmfolks]

It makes me think it's a spawing event.

Of the snails? I did just switch to a higher quality phyto too, so "they" could be reacting to that

You should try to remove the snails. The mucous nets can irritate corals and make them stay closed up. I just pulled one from my tank yesterday. Looked like this

The red swirly thing is the snail. This one was irritating the zoas and making them stay closed.
