Monti problem

[J8851]

My montipora digitia that i've had for 4 months for the past 2 days has not opened. I moved it to very minimal flow and it still hasn't opened. I haven't introduced anything into the tank for a while about a month. I took it out and examined it and there were no signs of bugs. I did do a water change last friday but it appeared to be fine until 2 days ago. Any clue what this could be?
I'm running 3x250W MH 12k Reeflux.

.....maybe a fish?

just out of curiosity, what brand of salt did you use during that last water change? I too have a digi that I've had for a while and is recently unhappy... about two days after a water change using a new brand of salt. Not saying the salt is the reason, just trying to narrow down possibilities.

I would think fish also. Anything new or any nipper type fish in there that maybe the polyps started to look cuisine to a fish all of a sudden.
