Yellow toad stool mushroom coral

[bigdogeder]

Hey folks I have a yellow mushroom coral in my tank that isn't fully opened. It was but today didn't open all the way. I did water tests and got the following
Ammonia 0
Nitrite 0
Nitrate 20 ppm
Sg 1.24
Temp 81
It is the same as it has been. My other corals are fine. I have a pulsing Xenia a frogspawn and a goniperia plus some zoos. All the others are fully open. Any ideas would be helpful. I have I in the middle of the tank as far a water column. Shod I move it closer to the top of the live rock I have Thanks for any help you guys and gals can provide b

I have had it a little over a week. It just worried me as I wasnt sure if I should move it. As I said all the others are doing great I was just wondering if I should move it lower or higher on the tank I will leave it be for the time being Thanks for the help.

I checked my log book and the only change was the temp was 3 degrees higher today than Sunday when I last checked could this have caused this ? It was really hot today in Baltimore where I live and we didn't have the air on in the house. Thanks again.
