Cloudy eyes + dark iris + not eating for 1 week

Noticed that RTG pupil surrounding seems abit 'translucent' this morning before work.
Just got back and seems like it had developed into slightly cloudy eye symptom.

Last night noticed that aro seems easily frightened, like when i approach it, it would suddenly turn or dart quickly, once it almost jumped.

About 2 weeks back when my tank was affected by high nitrites (http://www.arofanatics.com.sg/forums....php?t=313703), noticed aro's iris seems to be getting abit dark colouration. it changed from the usual greenish/golden colour to now slightly brownish colour. It stopped eating few days later.

Till now its about 1 week+ since it last ate. Although previously during low ph6.5 and high ammonia, its still eating, but now with better water parameters but higher ph, its not eating.

My 522 80%-filled tank has just completed cycling few days ago and yesterday's water parameter as follows:
ph 7.6
ammonia 0mg/l
nitrite NO2 0mg/l
nitrate NO3 25mg/l

Questions:
1) Should i remove the 1kg zeolites (been in tank around 1 month during high ammonia phase) and replace it?
2) Should i lower the ph as the rtg seems to be more comfortable with around slightly less than ph7.
3) My usual practice is to wc at least once per week, I intend to wc 20% tomorrow with ~30L of aged water + some tap water. Is there anything i should take note of?
4) I'm leaving sg for 5 days next week. What should i do to prepare in these few day as there would not be anyone to help me with wc.

Any advice from bros and sis greatly appreciated..

Just to add more info...

Bare tank 522 (80% filled) with single layer ohf + 2260 canister.

Only 1 aro, no tank mates now. Previous 2 SD kena whacked by aro till i have to remove them (but they RIP in quarantine tank). After no more tank mates, aro stopped eating as previously its habit is to chase after SD and snatch food from it.

let me know if u need more info.. i'm getting worried cos will be in sg till monday only, so any actions need to be taken fast..

thanks in advance for advices.

hi bro, thanks for your reply. i don't use heater as my water feels warm as compared to my other tank. if i use multicure, i have to remove the zeolites right?

thanks!
sis kappo

Today's water parameter:
ph 7.8
ammonia 0mg/l
nitrite NO2 0mg/l
25mg/l > nitrate NO3 > 50mgl

You can try to put in the black water to calm the aro, I have one bottle of tetra black water, if you want to try can pass to you.

The photo few days back was before the cloudy eye problem, its just the iris darkening.
The 2 photos posted this morning.. hmm.. maybe due to angle or lighting so the 2 photos seems a little bit different?

Thanks for the offer.

Thanks for the offer.
I still have some aquamedi black water extract and ktp leaves as well as some multicure left.
If not enough, can go to y618 or aquastar later.. only if urgent to get supplies then will call you. Appreciate your offer

Anyway, I intend to do the usual 20% wc later with salt and black water extract and monitor first.. if by tomorrow no improvement then maybe consider multicure.

Do you think if its ok to remove 20% of my CC as i think the ph maybe too high for aro's comfort?
Should i remove the zeolites as well since they're >1mth old and was in there during the high ammonia phase?

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.
