I got this acan last week and for the first few days it was super puffy and colorful but now it looks like that. I have it at the bottom of the tank with low light and low flow. All the other corals and fish are doing well. My water params are 0 ammonia, 0 nitrite, 10 nitrate, .15 phos, 9.9kh, i dont have calcium test or mag test yet.
