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.

any advices? aro swimming seems not graceful now, and still not eating, eyes still cloudy..

I intend to add more multicure tomorrow + some salt..
what i need to prepare when i'm away?

thanks.

last night added 70ml multicure and set heater at 31 degC, but aro's not improving at all, it seems to be having some difficulty swimming now.. sigh...

i'm very tired and stressed mentally thinking of how to how to improve aro's condition within this last 12hrs before i leave.

i don't know the ammonia and nitrite increase could it be due to the green tinge in the water due to multicure.. anyway this is today's water parameters:
ph 7.7
ammonia 0.25mg/l
nitrite no2 0.5mg/l
25mg/l > nitrate NO3 > 50mgl

this is the picture of the white fuzzy stuff on the gill plate, i don't know if its clear enough.

Help, help..

Just came back from dinner and noticed that aro flipped belly up.
But its still alive.

Now i'm using my hands to support it to straighten up near the air stones..

Any urgent medical remedy i can try?

Hi mod, can close this thread pls.
thank you.
