help cloudy eyes on id shark

[arowana man]

my irridesent sharks,2 of them have foggy/cloudy eyes. is this normal or eye clout

 

[killerfish]

sounds like eye cloud its not normal but its treatable try a little salt and warm the tank a little if that doesn't help or you don't wan't to mess with that just pick up some melafix and that will cure it right up
