I have a colt that's generally in the 7-8" range. Lately, it's been opening (full brown polyps out), but deflating (about 2-3" tall instead of 7", stalk looks week, branches bent and limp).
Nothing significant has changed in the tank - same location, same light, same flow. Bulbs are PC (4x65W), about 7 months old. Added some ordinary Turbo snails and hermits, just to replenish what had disappeared over time.
Everything else in the tank except a GSP cluster looks fine - that cluster also isn't opening, which is unusual. All inverts, fish, and other soft corals are fine.
My hunch is that there's some outside pollution - my wife generally burns a lot of candles in that room, any chance that's irritating the system? Anyone have any other ideas?
