Hi Sayid,

That's such a shame as it is a nice looking fish. Generally cloudy eyes are associated with poor water conditions and a bacterial infection so if it had a bout of trouble previously, then this might be a related condition. Seems like you are doing all you can to get it back to health, normally head standers are difficult to get back to normal again so good work.
As you have treated with several methods so far and it still has these white spots in the eyes ( I am assuming they are under the outer lens ) I am thinking the damage is too far gone and it has some degree of blindness. This could also be the reason it isn't able to eat so well. A bit like us humans with a cataract in both eyes. See what happens after the next round of meds and report back. Good luck my friend.
