What is happening to my mushroom

[corinateut]

Hello everyone,
For 2 days I noticed that under my mushrooms some bubble “skin” is showing for few minutes usually night time.

Anyone know what is this or what is causing?

Thank you

Is that anemone crab always around it or just a coencidence?

Normally when the pedal area inflates, they are trying to move. The crab could be annoying it.

Be careful where it goes as discosomas can quickly reproduce and become a neussiance as they will kill almost any coral they touch.

I've seen shrooms do all kinds of odd things, sometimes irritated, sometimes on the move and sometimes letting go (irritatingwhen this happens). Like was already said, keep an eye on it and I'd also watch that crab! Nice shroom, btw!

The crab settled few days ago on mushroom.
he is grifting. About 2-3 weeks ago we lost our anemone in wave maker.
at first he was sitting exactly where his anemone died and now is just moving around.
thank you
