Goldflake still frantically glass surfing

[Flame2hawk]

After copper treatment Goldflake is glass surfing more than ever. I wonder whether a “wound like” blemish below the last row of flakes between the right side fin and lower fin, which I tried to capture in the 2 photos might be the culprit? Does anyone know what it might be? It’s whitish and does have faint scratch type lines and then some small faint white dots that look a little like Lymph. It hasn’t gotten worst or better in the 10 days that I’ve been observing it. Thoughts and suggestions welcomed as I try to save my favorite fish....Its exhausting to watch his glass surfing so he’s got to be also exhausted.....he did not eat today but has been eating sparingly the days before that.

Maybe keep switching it up until he forms a new routine? Have you tried a dark towel over the glass to interfere with any reflection? Move some rocks? Change where a power head blows?
