I'd lean toward water quality too. Even if params are good, dissolved organics can irritate fins. Try adding some Indian almond leaves—they've got antibacterial properties and might help.


Second this. Also, consider a UV sterilizer if you're battling persistent bacterial issues. They're pricey ...

Could be bacterial if the water's clean and there's no aggression. Try upping the water changes to 50% for a week and see if it improves. Also, what's your filter setup? A clogged filter can mess with water quality even if params look good.

I've had my discus for a while now, they're not juveniles anymore, and after a massive tank cleanup, I decided to bump up the temperature in my discus tank from 82F to 86F. I've also got cardinals, sterbai, rummy nose, and bristlenose plecos in there.

I'm aware that higher temps increase metabolism ...
