ID Please! Weird Transparent Stuff

[meganias123]

I'm not sure what this stuff is... it is completely transparent, no coloration and moves in a wavelike motion clinging onto my LR... it seems to have long and short strands but it's in clumps and seems to prefer low lighting bc I don't see it anywhere besides in caves and under ledges. Sort of resembles thin, whispy hair underwater... except it's transparent.
Does anyone have an idea of what this could be/is?
I've been looking around on the Web and can't find anything...
I thought maybe it was eggs of some kind but I only have a pair of clowns (doesn't fit the description), a single bicolor blenny, 1 skunk cleaner shrimp, some hermits (I've read they keep their eggs inside their shells?), and 3 nerite, 3 nassarius, 2 turbo, 2 cerith, 2 astrea snails... also some tiny (salt-sized) copepods and amphipods.

Could it be a snail trail? Does any of your substrate get stuck in it? My jumbo nassarius leave gooey waving trails here and there and they do go away in a matter of hours. Or maybe you have a light colored form of green hair algae. Maybe a new strand of algae would be lighter in color, or even transparent, given it hasn't absorbed much light yet.

Nah, i have 3 nassarius snails and I know the gooey stuff you're talking about the stuff I'm talking about is surrounding some holes and dimly-lit caves of my live rock... places my nassarius don't go. Honestly, my nassarius don't move around much, mostly stay in the sandbed or once in a while I'll see one climbing up the wall of my aquarium lol (leaving behind that slime stuff you mentioned). The stuff I'm concerned about does trap detritus and sand particles, along with my tiny copepods in it's jelly-like, hairy tissue or whatever it is. It could be some form of algae but I've been considering the possibility of it being some species of hydroid. I have the little "eggs l" or seedlings of hydroids in my aquarium for a month or so and haven't noticed them doing anything but multiplying and now this transparent stuff. The more I look at it, the more it reminds me of how a jellyfish looks and moves... except the fact that its rooting itself in the shadows of my liverock surfaces.
By the way, Thanks for the response!

I have that too. I call it ghost algae. Haven't found much on it. If it's the same thing I have, then it almost looks like smoke under the ledges or something. I don't even know if it's a true algae, but I'm following along to see what the experts say. [emoji38]
I did Google "ghost algae" and got an article but I still don't know how to get rid of it or even if it's bad. (I'm guessing yes because I never get the good stuff. Haha.)

I'll take a guess!

Maybe, it's a a gooey net secreted by a worm hidden in your live rock, like an underwater version of a spider web. You said pods were getting trapped in it.

I'm not sure how you could confirm this, but you could start by observing it at night with a flash light. Maybe see if pods that are trapped one day disappear the next.

Weird stuff! Good luck!

It definitely appears to be moving due to the current.
My guess would be it's mucus nets created by worms, but it's hard to tell from this distance. Perhaps pull out a small rock and get some pictures of it in white light?

 

[meganias123]

Haha thanks for the responses guys! It's been a little while and I no longer have any in my tank. I didn't do anything to get rid of it... just kinda ignored it since it didn't seem to bother any of my critters.

Vermatid snail would be my guess seems pretty obvious to me......:worried2:
