One of my discus had cloudy eyes that turned into popeyes and it is now in stable condition. It actually spawned, but its eyes are still cloudy and hasn't fully cleared up yet? How long does it take?
I noticed another discus of mine, a part of its side of its eye has a white speck now. I don't know why these bouts of sicknesses keep happening in my tank.
Quote from Colin Powell
"There are no secrets to success; don’t waste time looking for them. Success is the result of perfection, hard work, learning from failure, loyalty to those for whom you work, and persistence. You must be ready for opportunity when it comes"
More water changes should clear the problem , but
if the cloudy becomes more white like the color of
egg white most likely it's permanent.
