I looked up Exopthalmia in a couple of reference books and came up with the
following -
Popeye (Exopthalmia)
Micobacteriosis
Exophiala Disease
Gas Bubble Trauma
Icthyophonus Disease
Vibriosis
If the popeye occurs after a water change I would put down GBT as my first
suspect. You don9t see it in home aquaria much but it is common in large
public aquaria. If you get your water out of the system and aerate it for
a day before water change all supersaturated gases should be removed.
Sometimes when the pressure goes off a liquid with loads of gas it goes
milky.
Cheers
