What is this?

[irishpenny]

This morning I saw these swiggley lines on my glass tank. What is this? I noticed that one of the scarlet skunk shrimp is missing..had two. I saw the shell near the rock, but no shrimp. Would these swiggley lines have anything to so with the missing shrimp. I have 2 clownfishes, one coral beauty and one blue tang...all have been getting along fine. Also some snails.
Do I need to remove these swiggly lines?
I hope I can post a pic so that you can see it. If it doesn't work, anyone have any idea what I may be talking about?

Do you have any snails? Maybe Trochus snail eggs...

Snail eggs, most likely cerith eggs.

If it snail eggs...do I remove them? I do have snails in there..not sure of the name.

If you don't want anymore snails, remove them.... but chances are most of them will become fish food anyway.

Sure your shrimp isn't still alive? It could have just shedded its exoskeleton.

Well, I read up that the shrimp will lose it's shell or skin...think the term is molting? I have no more info about them. I don't see it anywhere in the tank...was told they hide. I can't find more info about them...how long do they hide before they come out again. How often do they "molt"? I think my fishes are missing their daily cleaning...
I have learned from this site and still will be learning more. Thanks for any info.
