Hello, my anemone “threw up” something that look like a silk or spider web after a water change and closed, i took a picture but it disappeared from my gallery.
Anyone know what it is? Should i be worried?

Do you have pictures?

Perhaps waste. Pictures would be helpful if you have any!

I took the picture because i was worried, but today it disappeared from my gallery.
If it happens again, i will take another picture

Expelling Zooxanthellae most likely.

I had a trachy that would spit out cyano/dinos when my tank was going through a rough spot! It was weird but somewhat cool to see. Oddly enough the trachy didn’t lose a beat during this time and continued to grow! I sadly lost it when I moved though.
