What's up with my Sebae??

[reefkpr123]

I have a 29g reef with a 3...or so hob ref.
150watt MH 14k
96 watt actinic
I have a Sebae Anemone that I bought at ***** about a year or so ago. It has been doing very well. It has at least doubled in size, and has gotten back a lot of it's tanish brown color that Sebae's have.
Until recently.....
About a month ago, over night, it moved from the the front of the rock that it was attached to...all the way around to the back....tucked up into a dark spot on the backside of the rock. I couldn't even see him....I found him there by touch.
So I let it go for about 2 weeks...and then came time to do a water change, so I flipped the rock over (of course this meant re-arranging the entire tank), did the water change, and just let it go for a while longer. At least I could see him now.
So now, two weeks later, he's still attached to the rock, but is only about the size of a silver dollar, and looks like he's bleached out. I know with Sebae's, that the darker color is an indication of good health, and bleached indicates malnutrition/starvation.
So what's up with this guy? Why did he take such a sudden nosedive??

Hard to say but sounds like, since you have sufficient lighting, that there must be some kine of water quality issue.

+1...what are your water parameters? Have you changed anything?

Nitrates are slightly high.....20ppm, maybe?
Other params all good.
Like I said.....he seemed perfectly fine one day...and not fine at all the next.
Not sure what to make of it....
