Greenish patches on skin?

[Pamuzinda]

Hi everyone,

My lotl called Nessi is 6 years old now, and recovering from being in quite a bad state.
She eats well, tail is straight, and seems to be showing relaxed and normal behavior, which leads me to believe she is doing well. The aquarium is clean and the parameters seem fine, by the way.

My question is about her skin; she currently has patches on her head and fin. They are looking greenish. As if algae soaked into her skin. The patches are not elevated at all, not fluffy, really no texture to it. I have tried to read up on skin problems to find what it could be, but none of the sources ever talk about greenish looking patches.

They are really just small greenish looking patches on her otherwise dark greyish looking skin.

Does anyone have a clue what it could be off of this marvelous description?

That's one of the options I had in mind. Her underside seems to be lighter grey than the top of her body. The darker area has black spots scattered all over, while the lighter areas seem completely smooth colour wise.

I have taken a picture to show what the patches look like. Also, I know her gills and her eyes look bad, but could it be connected to the source of the weird coloured bits?
