Cloudy eyes + dark iris + not eating for 1 week

Last night i removed the zeollites and added 50ml multicure to my 522 80% filled tank as the cloudy eye symtom did not improve and i noticed some fine fuzzy like stuff (looks like white skin peeling on the right side of gill plate) that is noticable only if you look carefully at aro from the front.. I don't know if its any cause for concern

Also noticed that aro tends to open and close mouth partially at intervals, i don't know if its any signs but the tank aeration is at its max now.

Perhaps due to not eating for 2 weeks now, maybe aro is weak so sometimes when it swims, sometimes it swims with a posture of head slightly tilted 15deg downwards. i don't know if its any cause for concern too.

Need advice urgently as i will be leaving sg for in 2 days time and very worried about aro's condition.

Thank you.
