Brown jelly or something else?

[KendraB]

Excuse the double post, but I figured out how to upload a video finally, and I'm curious about what this is.

This stuff popped up on a small piece of broken off GSP a few nights ago, and has tripled in size since. (It's still tiny, probably half the size of a dime)

I've looked at lots of different pictures of brown jelly, but none of it looks like this.

Does it have antenna? It looked like it to me but I have old eyes

Maybe some kind of algae or bacteria where the broken off piece of GSP is dying or rotting.... Not really sure about any of that. Sorry

Maybe a close up pic can shed some more light on it.

Glad to know it's not brown jelly.

And it is really strange, and I can't find one single post anywhere of anything that looks remotely like it. No antenna, it seems to be growing out of the rock. At one point, it was two small pieces and I guess they grew into each other.

If you don't trust it suck it out as you don't want it to spread in your tank, good or bad if you didn't put it in and it's ugly it has to go.

Looks like a weird piece of blowing cyanobacteria, just an odd shape. Cyano would match up with the growth you've seen as well.
