Should I try FW dipping him, would they show in the water?If a fish just has one cloudy eye, it is usually due to an injury. With two cloudy eyes, either the fish was REALLY unlucky and got banged up twice, or it has Neobenedenia flukes. Flame hawks are very susceptible to Neo, so that would be my best guess.
You can try Prazipro in your tank, dosed 3 times, 8 days apart, with good aeration, but Neobenedenia is tough to kill off because the eggs are resistant to drugs. I've had my best success by running all of the fish at half salinity (1.012) for 30 days. Of course, you can't do that with invertebrates in the tank,
