Spider webs under water?

[SashimiTurtle]

Started my nano up with live rock. Not that dead stuff you buy BRS, but actual living rock from the actual ocean. An LFS near me has a huge selection for $6/lb.

Anyway, I've seen these red barnicle like things on one rock but I thought they were dead for the last 3 months until today.

Vermetid snails. I think.

Vermetid snails. They cast those nets to get food from the water column.

They can irritate corals if there's enough of them (and there will be lots of them if you overfeed), but are otherwise okay

Those are a type of snail, I can't remember the name. They put out those long tenicles. Their kind of a neusense, but I'm not sure what you do about them. Im going to follow to see what everyone else has to say, as I have them also.

 

[ReeferMaddness843]

Vermatid snails. I agree.
If get pesky, easiest way to resolve/remove is to cover their opening on the tube with super glue. If you have the time, the most surefire way to remove as well as prevent from poking you whenever go to pull off some live rock is to actually use a pair of fingernail clippers or side cutters and clip them off. You have to get all the way to the base of the rock, otherwise they'll just retract into their home and rebuild the shell.
Like others said, not too much of an issue. Aside from the "webbing" possibly irritating corals when touched. If over feeding, they will potentially become a plague.

 

[SashimiTurtle]

Thanks guys. They are near a piece of recovering forest fire digi, but the current pulls the webs away. I'll remember the super glue if they get out of hand. No need to worry about over feeding just yet, no fish.

So, Google search finds that they absolutely wreak havoc on SPS corals, and that's 90% of what I have in the tank. These little gastropods must die. Time to get the cutting dikes out.

I have a couple is these vermitid snails and they are not much of a problem. The are actually pretty interesting to watch. I would say the irritation is somewhat limited. I adjusted the flow a bit to cause the "webs" to go a different direction away from a couple corals.

 

[|FATHOM|]

I've had these irritate zoas in the past. I simply crush the tube with some bone sheers when I see them

 

[saltyfilmfolks]

They sting some things and not others. The sps mine was living in it didn't sting, but a couple of close corals it did.

I put some super glue on a dab of coral putty. Problem solved.

Leave them there and go out to dinner, try the Merlot. Those snails are normal and natural like high heels on Supermodels. They won't hurt anything and you will never get all of them out anyway.
If you play RAP music they may go into their tubes.

Agreed. I left mine for over a year. I named it bob.

Bob started messing with my wife's coral. I tried talking sense into him.

I have 8,639 of them and they never bother anything, not even their great, great, great grand Nieces.

We just smash them at the base and within the hour the arrow crab finds and eats them

 

[SashimiTurtle]

I ended up taking my small dikes and cutting down until I killed them... I didn't like the spider webs all over the tank. There is a pom pom crab, minus two pom poms..., and squat lobster in the tank, but I never see them.
