Help with diagnosis

[ChanceB2002]

Hello, I have had a Fluval EVO for about three months now, when setting the tank up I used some live rock from petco which unknowingly and sadly had some Ich on it which was introduced to my system. I want fallow for a total of 56 days I kept my Display tanks heat elevated at 82 to 86 degrees for the entirety of the fallow and I replaced my sand bed completely, I also put my fish through Copper and did the Tank transfer method to just be extra per captious. I reintroduced my fish into the display tank an one of my clowns has these white spots on him again it doesn’t look like ich to me only because it doesn’t look like the spots it had before but these are more raised and flaky and you can tell he’s got a lot of extra mucus on him , he is acting normal and eating normal he just looks sick. Any help would be appreciated and thank you in advance

could you post a 30 second video to youtube and paste the link here? As well as your current parameters. That will be the easiest way to get you help with a diagnosis
