While I've been on MR for years, I've bought my first LPS coral just a month ago. It was a beautiful Euphyllia with 3 colonies. I first placed it on the substrate, but after a few weeks noticed what looked like dead polyps falling off, so I quickly moved it to a rock higher up. It went back to looking good and healthy until this morning when one colony completely retracted, see picture.
What's going on? What's the potential diagnosis and remedy?
-------About my tank-------
36 gallon tank about 9 years old.
3 Oscellaris and 1 skunk clown. 3-5 blue leg hermits, a few naussirus snails, a turbo snail, a green BTA anemone and a long tentacled anemone (also btw not doing well).
Filter: I do a 10% weekly water change. Canister filter, about 30 lbs live rock and 30 lbs mature live sand. They have white bristle worms in them. Filter contains bio media, some carbon and some phosgaurd. No sump or skimmer.
Equipment: Hydor powerhead, Marineland Heater, Orbit marine lights. Hydor Ato with 10 gallon reservoir.
Parameters: 74 degrees. checked with Red Sea test kit this week:
Ca 500+ ppm, Alk 5.5 dKh, Magnesium 1500 ppm, pH 8.3.Other parameters unavailable. I'm not sure how accurate the test is this time because the parameters seemed overly high.
