Why do discus fins look clamped?

[picker]

Noticed my discus have clamped fins lately. Water params are good, 0 ammonia, 0 nitrite, nitrate around 10 ppm. Tank is 75 gallons, temp at 84°F, running a Fluval FX6. They're about 6 months old, fed beef heart mix twice daily. Any ideas what's up?

Clamped fins can be a stress thing, bro. You got any new tankmates? Sometimes even a sketchy decoration can mess with them. My discus did that when I added a new piece of driftwood.

Yeah, stress is a big one. Also check your water changes. If you're slacking, the TDS might be creeping up. I do 50% changes twice a week with RO water, keeps 'em happy. What's your WC routine?

I agree with luxe! Water changes are key. My discus perked up when I switched to RO. How often do you change the water, picker?

Mine did that when the temp dropped. Heater was acting up. You sure your heater's reliable? Cheap ones can be a nightmare.

Could be parasites, man. Mine had clamped fins and it turned out to be gill flukes. Treated with PraziPro and they chilled out. You see any scratching or weird breathing?

Thanks for the tips, everyone. I do 30% changes weekly, but maybe I'll bump it up. Heater's a Eheim Jager, seems solid. No new tankmates or decor. Gonna check for parasites though.

Yep, weekly might not cut it. Discus are divas, need that clean water. Try upping the changes and see if they loosen up.

Eheim's a good brand, but still worth double checking. Parasites are a solid guess too. If it's not that, maybe they're just being fussy. Discus can have weird vibes sometimes.
