Silver dollar whith eye problem???

hI guys, I have noticed a last week that my silver dollars 3 of them have some white "bag" around the eyes? All three with the same problem in the same side.... the guy in my pet store told me that it could be some sort of bacteria? I have been treating them with (waterlife- gill e body fluked) <-- his indication..... it's the 4th day now and nothing had changed.... I do think that it's not bacteria or any sort of illness as they are all active and acting as they should, but I noticed that all my silver dollar keeping swimming close to the glass and pretty much always rubbing the eye over the glass... what you guys think it is and any idea about what should I do?

ALL my fishes look very healthy and active apart from the eye problem in those 3 silver dollars

its a 300L - 80 gallon tank with 9 silver (4 silver shark TEMPORARY) 10 corydoras and 3 albino bn pleco...

ammonia 0
no² 0
no³ 50-70 -------cant change that as my tap water have around 40-50ppm from the tap...

water change every 5...6 days around 70 - 80L.


thank you !!!

sorry for the long text!!

 

Oh wow, that is noticeable.

Why are they swimming that close to the glass? anything change inside or outside the tank?

I have 4 SDF since June. Sorry I have never seen that type of behavior or eye distortion.

 

I really don't know why they are always swimming that lose from the glass as they really have lots of space there.... :/

Looks like drop eye.
The cause of it is still hotly debated, but it’s agreed that drop eye is harmless. It’s usually a buildup of fatty tissues behind the eye that causes the eye to face downwards. There’s no medication that I know of that can get rid of it, but I think I remember of hearing about surgeries you could perform on your fish, but they’re pretty risky. Since drop eye doesn’t hurt your fish, I wouldn’t bother to try and risk surgery. It’s only mildly displeasing to the eye, after all.

Could be... but the eye still exactly in the same place and it's not popped out.. its literally just the extra "white skin" around the eye.... some days it look smaller and the next day, bigger... I don't know...

 

I'll try remove the plastic plants from it, so it's one less thing for they bump on...
