magnifica anemone Deflated... HELP?

[bsung413]

I have a magnificent anemone in my tank for about 3 years now.

It has been through tentacles chewed up by power head and recovers just fine, it's a tough guy.

However today morning I found its tentacles deflated looks pretty slapy unlike usual. But yesterday it was doing just fine ate too.

It's still attching it self with a rock and still pretty sticky, wondering if it normal?

The only thing I have done is i cleaned my LED glass cover it has like salt and water stain on.

Could this be an issues that lights suddenly got brighter and they are just adjusting it?

All my other corals seems fine tho

Much appreciated for your help or info

Thanks
