Do I have something to worry about?

[egunman]

When my lights went out last night, I was looking at my frogspawn when it was closed up and I noticed a bunch of what look like tube worms of some sort inbetween all of the branches. just wondering if they look like something I should be worried about. I have also noticed a couple growing on the rock. One of them has a long string coming out waving around in the water column. Any ideas would be great.

thanks

I'm not great at identifying things in terms of names etc but I think what you have there is something that I have had for years and will not cause harm to your corals. Some sort of tube worm that casts out a net for filter feeding I think. No worries, just another cool finding that makes this hobby so amazing.

Vermatid snails. Nothing really to worry about. You can break off the tubes if you want. Be careful not to cut yourself, as they're sharp

They would not dig holes in the skeleton would they? I have a candy cane that is starting to get them and I have noticed there are little holes all aroun it. The candy cane is starting to go down hill.

No I don't believe what you have there would cause any damage to a coral. You can, as returnofsid said, snap off the tubes there by kiiling them. If you want to do that to your candy cane as a way on confirming they are not the cause then go for it. I would be looking at other causes though. Always good to do a water change when things don't seem right and perhaps run some fresh carbon.
Good luck
