Of all my Corals, my Paly Grandis colony has been really unhappy for 2 weeks. They're shrunken, closed and one looks like it melted away. My daily parameters test within 5% of those listed in my Signature. The colony is on a rock "island" in a low flow eddy area which gets about 90 par for 6 hours in my schedule. They were happy here for months and suddenly closed up. No other corals are within 5 inches of them.
Because they are in an eddy, lots of food passes through their rock so I dont have any reason to believe theyre starving. They also get 2x week Reef Energy.
Their rock has some other critters, brittle stars, bristle worms, copapods, filter clams, emerald crab, and a few dozen tiny Vermitid snails which I smash when I get a chance but they were there since before I bought the colony.
HELP ME SAVE THE COLONY!!
I dont know what else may be going on
