Help on Yellow Matt - Dying??

[BarIzoN]

Hi,

Overnight my Yellow Sea Mat coral has became brownish, all closed and is thinner than ever!!

Whater parameters are normal, and all other corals doing good...

You have diatoms growing on it - this may be irritating it. Blow off with a turkey baster or similar device or remove with cotton swab. Note it may be that something else has caused them to close and the diatoms came afterward. Sometimes soft coral close for a few days to shed their coating. I'm not directly familiar with these if they do that. Hopefully others will chime in.

That makes all sense.

I'll carefully clean them up.

Thanks for the input!
