Have you tested your water?
Yes
If yes, what is your ammonia?
0-0.25
If yes, what is your nitrite?
0
If yes, what is your nitrate?
~10
If I did not test my water...
  1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.
Do you do water changes?
Yes
What percentage of water do you change?
41-50%
How frequently do you change your water?
Every week
If I do not change my water...
  1. ...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.
I'm sitting in the living room when I look up and notice something on Ursula's side. I'm about 93% sure it was not there as of 3 hours ago when I fed her and spent a while watching her. It was for sure not there 5 days ago, that's when I have the last good photo of her with no sign of anything. I've had problems with my guppies and one of my bettas in the last while so I'm really scared of health things lately. It looks like it has air bubbles (or glitter) trapped in/under it, and it moves towards and away from her body as she swims like it's only attached by one point. It almost looks like it might be a loose scale? Is that a thing?
General details- 4 inch young oscar alone in an 80 gallon tank, planted, FX4 filtered, 80 degrees, set up for 2 weeks so still very new. 0-0.25 ammonia, since it's a new setup I'm monitoring that closely, 0 nitrite, ~10 nitrate. Last water change done yesterday, 45%.
Hopefully these pictures can give a sense of it. It's confusing me.

May have scraped itself on something. Doesn't look fungal to me.

So that scale seems to have detached, but it looks like there's a similar thing on the other side. Also I might just be paranoid but I feel like I see a slight greyish tinge on some of her scales? Her behaviour is still normal. I added some stress guard.

Also here's what I was dealing with in my guppy tank in December and January, so you know why I'm so freaked. I actually didn't lose a single guppy and they've been clear for some time now.

I'm in Canada so I don't have many options for meds, if needed. I have some Kanaplex and Furan-2 let over from the guppies but barely enough for one dose of the whole 80 gallon. I also have some API super ick cure which is less useful than in the US, it's missing the main antifungal. I could buy melafix and pimafix but overall I've heard they're crap.

I think it’s getting worse. New in the last several hours is another white spot, it looks like a dent and not something loose. Really scared it’s lateral line erosion. 2A393081-A8E5-439D-920D-3B7D212FE52D.jpeg
