SPS Not Opening? Help Please!

[ReefWaters]

I recently moved my set up. It has been running smoothly for a week now.

All my SPS frags are opening up nicely except one. It has not opened since the move. Im not sure of the species yet but I have attached a bad picture. Ill learn how to take pictures some other day. Right now, it is very high in the tank and I have not moved it.

Should I be concerned yet?

Some info:

The coloration of the frag under my light is a light pale green with the polyps closed.
24' x 24' surface area - 400 watt 10K XM, 2x75w VHO Super Actinics
PH 8.1
Temp 78F
SG 1.026

does it open up at night? a lot of corals open up at night and not much during the day. what are you alk and Ca levels? i look at these if things are looking funny. i also test both of these at least once a week. another thing to look for are tiny red bugs on the coral.

Ca is at 420
alk was at 9 dKH a few days ago
The lights went out about 30 minutes ago but it still hasnt opened up.
Ill check for red bugs tomorrow and check it in the morning before the lights come on.

You may want to move it down. I had a bottle brush acro that I placed high up, after being low in the tank, and noticed that it wasn't opening anymore. Even at night, I didn't really see much. So I moved it from high up in the tank to the sand bed.. within 3 days, the acro started to show it's polyps again (bleached polyps). It has been a few weeks now, and the coral is doing wonderfully. The polyps are normal color again, and extending. Some corals may love the light, but can still be to high in a tank, from my experience.

Thanks for the reply Jeremy1973.

I think I will try that tonight when I get home. Unless for some reason it has decided to open up, but I doubt it.

Ill try to post the results to this thread if and when the little guy perks up.


Thanks again,
