Hi everyone! Got these white spots on PC rainbow about 2 weeks ago. Coral seems happy and has full polyp extension. Coral is encrusting and has been I the tank for about 6 months. I’m thinking those spots are from fish damaging it. Don’t see red bugs or flat worms. Parameters: salinity 35, alkalinity 8.5. Phos 0.0. Nitrate 20 ppm. Temp 79. Calcium 420. Any ideas?
