Mushroom question

[Pow85]

Hi, do mushroom corals close up at night as I have found something growing on my live rock that looks a little like one that seems to close up when the lights are out. I can't get a good look at it as it's round the back of my tank so can only see it in the reflection on the glass which also means I can't get a picture of it.

Thanks

Depends on the shroom. Some like to stay open, others close up. What kind do you have?

I'm not sure, it's round the back of my tank so I can't get a good look at it. I can only see it in the reflection on the glass. All I can tell you is that it's dark purple. Sod's law though that I get a coral appear on my live rock and it's round the back where I can barely see it.

Yes. Mine tend to shrink up smaller at night
