I noticed multiple pin holes kind of thing on blood parrot head since 3 days. full tank cleaning on last Thursday- almost a week.
Tested Nitrates, AMmonia to be Zero and nitrites to be 20. Prior tank cleaning only difference is nitrites at 60/80.
The affected parrot been blind for almost 7 months. 6 months in to the current tank. Prior becomingd during blind it didn’t eat for almost a two months.
Rest of 4 parrots also not eating since last water change, currently using Epsom salt in to the tank on alternate day.
I do 50% water change on a weekly basis with gravel vacuum. During water changes, Seachem Safe and Blue liquid (guess Methylene) are used per dosage for 200ltrs.
Btw- one of its eye seems to be deteriorated inside which initially was looking like a layer but now like a pin hole between the silver shell ( eye frame) which grown heavy.
Attached the pic. Any advise?
