Hitchhiker ID Needed - Short Video

[Beverly]

We have this red blob thing growing from one of our rocks. It appeared on the rock a couple of months after we moved it from our 37g to our 120g. Don't know why it didn't grow in the 37g.

Anyway, the blob is getting bigger. The blob brushes up against a devil's hand, but does not sting it. Any ideas of what kind of animal this is?

Neato! I have no idea what it is. I could have done without the music though

I have no idea, my guess is that its cotton candy algae but I could be completly wrong.

in my studies i have grown and seen a number of large types of ocean cycanobacteria that form a gelly like colonies...
if you can get part of it under a microscope it would be really cool

Dang. No microscope available.

Tell me more about the cyano jelly stuff, if you can. Pics would be great.

The thing in my tank reminds me of some kind of anemone, if that helps. If you look closely at the video, you can see it is not one big blob, but has nodules. There appears to be air bubbles inside the nodules, though I don't think they are apparent in the video.

this might be a bit off topic but.... kinda looked like a balet dance you were doing with your finger and the blob...

soooo pretty
