Worm drilling LR?

[WildFlower]

Not able to download a pic yet, so I will describe best I can. Not sure if this is a worm or what, but yesterday in the bottom corner of the tank coming off the LR, I could see stringers/tentacles? They are thin, long, brownish colored, they seem to kind of curl and move at their will, does not look like waterflow is moving the stringers/tentacles. It looks like a white substance is being passed or is sliding down the strings, it has created a small mound on the sand bottom.

Because of the position of the LR (I've got a bunch) I can not see where this thing may be attached to the LR. Yesterday when I got home and saw this thing, my light was on. Got up this morning and turned lights on, it was still building it's mound, but within 5 minutes of the lights being on it disappeared.

Does this sound like a worm of some sort drilling out my LR? Whatever this thing is, what the heck should I do with it?

Sounds like either a spaghetti worm or vermetid snails. The spaghetti worm will protrude from a hole in the rock and extend multiple arms it uses to capture detritus and small prey animals from the water and surrounding sand. A vermetid snail will protrude from a calcerous tube jutting from the rock. The snail excretes a mucus web that can look similar to the spaghetti worm if it's not visually in the clear.

From what you describe, I'd be more inclined to think spaghetti worm.
