Sick male bristlenose

[Shinnok]

Hi all,

my bristelnose has developed this mouldy, grey growth on the back of its head and its body.
What is this and how can I treat it?

I have been using esha 2000 on a double dose (contains copper2) in a 15l bucket with airstone and cycled sponge for the last three days. Small improvement as the eyes are no longer white (white like eyes of a steamed fish).

Looks like some scraped scales. Suggest some api fungus cure. If not available can try some hydrogen peroxide on a qtip. Clean water.

Thanks! Will try that.
