All our corals are starting to flourish again, all the polyps are out and extended. Figures, I have a bad rash of coral die off in which I lost 90% of my corals, and now my fish are dropping off.
I wonder if a lack of cleaner shrimp could be contributing? We've always had cleaner shrimp until about 2 months ago.
