Closed Colt Coral

I have a piece of rock with three seperate Colt Corals on it, and the biggest of the three is extended, but the actual feeding polyps are closed. The other two are doing fine, which is why I'm puzzled. It's been this way for four days now, and it's never stayed closed this long. Any ideas why this is?

the conditions are great, no ammonia or nitrite, 0.5 ppm nitrate, everything else in check as well. It's under power compacts, and have brains doing great under them.
