Mushroom help maybe?

[Jay Z]

3 days ago I noticed one of my mushrooms starting to fluoresce around it’s mouth hole. Didn’t think nothing of it. Today it’s about the size of a dime. Included pictures show 2 mushrooms. One with the new aqua green center and the one below it. I took the picture at feeding time so they are shrunk up some. Almost look like thick strings? I don’t know. Put in a hour or so on google, couldn't come up with anything.

And on a side note my green (like same color) carpet anemone went missing 4 days ago. A mushroom couldn’t eat that, could it?

Those look like mesenterial filaments. Sometimes it's a sign of an unhappy mushroom.

My cleaner shrimp have been perching on them for the last 2 weeks. Maybe they had enough.

That would be cool to see.

We have a winner! She was splitting!

Thanks!
