Where did your rocks come from?
Do you have any coral in the tank?

Looks like a Spaghetti worm, good guys.

spaghetti worms live in rocks or sand. I don’t think they do that on the glass

I got my rocks from my LFS. I have no livestock in the tank at all just sand and rock. They are only on glass body long like a worm but still tiny. Looks like little tentacles flowing everywhere and crawling around on glass like a snail. I have no idea. I’ll try to get better pic.

Do they move around? If not, could be hydroids (harmless)

 

[bigsmoke]

Yes they are moving around on glass like snails

AHHHH heck no.... That would freak me out. I would not be sleeping in a house with a tank fill of magical water spiders.

 

[bigsmoke]

Little bit better pic. I can’t find anything that looks exactly like them.

 

[bigsmoke]

Has more tentacles than you can see in pic.

 

[Jman76]

Does it look like this?

 

[bigsmoke]

YES. But looks smaller without any orange in body. But that’s dang close

 

[Jman76]

Maybe its a sign of age? The one i had was pretty big and had mostly orange/clear body.

 

[bigsmoke]

Well my tanks only 3 weeks old so I guess we will see what they become lol. So far I’ve had the asteria stars. These and aptasia I’ve got to nuke.

Jman76. That is crazy. Was it just on your glass one day and you were like ‘what the heck...’ or had you been watching it for a few days and captured that great video?

 

[Jman76]

Ha, first of all that is not my video. But what I had looked EXACTLY like the video. And ya, I was a little freaked lol. Like a dummy I tossed it before I knew ‍
