I woke up to my leather coral all bent over, it was just fine then all of the sudden bent over. My water is 0 nitrate 0 phosphate 8.3 pH 10 KH 380 calcium (working to increase it) tank is 1.5 years old. Could this be a flatworm doing this? Is this normal behavior for a Leather? I love this coral I'm terribly worried about it. Someone I know said maybe take it out and treat it for flatworm exit for 30 minutes.... Thoughts, suggestions?
