sick oscar please help

[glen.1984]

over the last 2 weeks i have noticed that my oscars have these white spots appear but it doesnt look like white spot disease, the smaller oscar had them but they all healed up but the bigger one still has them. im wondering if its where they are jumping and hitting the lid?

first i did actually think it was white spot disease so treated it with waterlife - protozin (whitespot treatment). had no luck so i left it a few days and tried melfix, the affected areas would always heal but come back somewhere else. so then i started to wonder if it was some sort of parasite disease and tried aquarium salt with melafix and raised the temp to 85f (77f was there normal temp). so thats where ive got to now but im starting to wonder weather its just injury's from jumping around or hole in the head? ....... can anyone help me?

ive done water tests and ph tests and everything is fine, i keep the water clean but still i cant get rid of this. help would be much appreciated, glen.

I'm looking at the last pic. Doesn't look like injury from jumping on the lid to me. Do the holes look like pits? They look like it to me.

Water parameters?
Foods?
How often do you feed?

Don't treat fish with any meds until you are sure of what you're dealing with otherwise, you could harm your fish. Clearly not ich to me.

might be fungas or bacterial infection.

I disagree with it being fungal infection. Fungal infection is extremely rare.

ammonia - 0ppm nitrite - 0ppm nitrate - 10ppm

hikari cichlid gold, bloodworms, mussels, prawns. (alternate them) and feed once a day

Do Oscars have teeth on top and bottom? I ask because in the 4th pic those two marks seem rather precisely placed and they both seem curved.

Yes, they do. Interesting theory and very likely too. Seems despite the space there, they may also be lashing at each other. I wonder if a divider could stop the graze marks.
