My oscar recently jumped out of the tank as i was feeding it and after i put it back in the tank it seems like it is geting eaten by some kind of bacteria like white spots around the rear fins and then its starting to shread. I did a water change after that about 30% water change and it seems to have no effect any ideas? i dont want my oscar to be geting eaten by some bacteria.
water temp. 80 degrees
hes the only one in my 10 gallon tank
