I've had this for about a year. Have no idea what it is. Looks almost like the top of a jellyfish at first.
It hasn't spread and only recently started looking a little different.
I host hope it isn't harmful in anyway.

It was a hitchhiker on a piece of LR.

Looks like a hairy green shroom that lost its color.....

It was never green though. It was translucent before. And now they are turning brown

They do come in brown,tan,green,and purple, I had a piece of one tear off on a rock that I moved and because it was in very low light for awhile it turned clear took about 2 months to get its color back...

Great thanks! Glad it Isn't a pest. It was my first living invertebrate. I'm kinda attached to it. Lol
