I should of posted sooner. The 1st pic was about 10 days ago. 2nd pic is today. I've done several water changes. Everything water quality is good besides a 10ppm nitrate but, it's always that way. It's shrunk to a dime. Loosing tentacles. Not sticking to anything. What could be causing this? All my other coral besides 1 are doing great. I put in the cup last night hoping it would help. But nothing. Any suggestions would be great
