Hi, I went back and looked at the pictures and video - they just are not clear enough for me to even make a guess at what is going on. If you can get better images, that would help. Otherwise, as I mentioned, the fish may well have flukes, so you should treat with praziquantel 2 times, 8 days apart after the copper treatment is done.
Is the fish still eating well?
Is it gaining any weight?

i apologize for late reply, this is my first time being able to take a video of it without it hiding.
the fish is eating and grazing a lot. In terms of weight i am not sure…
As you can see on the video, it has a quiet large White spot on it. (At least compared to The usual size if ich)
