Hairy green mushroom staying closed all day

[GeorgiosT]

Hallo to Everyone!!!
I noticed a problem today with the hairy green mushroom I have. Soon as I open the lights it started a little bit to open up and then is closed up and stayed closed for the rest of the day. Here are the photos of how it was opened up yesterday and how it is today. I haven’t changed anything just made a water change the day before. It’s a week old and has been fine till now.

Okay, have you changed anything else? Light settings/height, water flow?

Nop. All that has stayed exactly the same

It looks very unhealthy. I cannot get my head around what could’ve happened.
