Trumpet coral - not opening

[Coralgurl]

I added a trumpet coral a week ago and it still hasn't opened up. It's placed low to middle, nothing around to bug it. My alk is a bit low but everything else is good. Other corals are all open. Does it just need time? There's no change in coloring or anything, just not inflated.

From my experience, trumpets usually open up at night when the main lights turned off, or when feeding. What kind of water flow is it getting? If there is no color change or obvious signs of issues, im sure its just fine :) My remain closed most of the time as well.

It's got good flow not too strong but enough. I had it on the sand for a few days, then moved it up a bit. Doesn't open when I feed either, but I can see it's mouths but no tentacles. It was open in the store..... I will watch it once the lights go off. Thanks!
