Smart move. Fluval's decent, but always good to verify. How often do you clean your filter media? Clogged media can cause temp swings.

Dark sand mimics their natural habitat best. I use Estes Marine Sand in my 180-gallon, and the colors pop. Filtration's handled by dual FX6s, and I change 25% water daily for fry. Adults get beef heart mix every morning, brine shrimp at night.


Absolutely. Noticed my Discus show better ...

Solid advice. Also, keep the tank setup simple at first. Don't rush to rescape until everything's stable.

Agree with throttling the FX4. I run mine at 50% for my 100g Discus tank. Also, ensure your driftwood isn't creating dead zones. Uneven flow can freak them out. What's your tank's footprint? Longer tanks distribute flow better.

Yo, sounds like your setup's mostly solid, but 4 months is sketchy if they're still tiny. What's the water change routine? Gotta do 50% at least twice a week for juvies. Also, beef heart's good but maybe cut the flakes, they're kinda weak for growth. Try more live food like blackworms if you can ...

My Discus are about 4 months old but seem way smaller than they should be. Tank is 75 gallons, temp at 84F, pH 6.8, 0 ammonia, 0 nitrite, nitrate under 10ppm. I feed them 4 times a day with a mix of flakes, frozen bloodworms, and beef heart. They eat fine but just don't grow. Any ideas?

Thanks for the suggestions, everyone. I'll try the terracotta first and see how it goes. Appreciate the help!

I'm setting up a breeding tank for my Discus and need ideas for DIY spawning cones. What materials work best? My tank is 40 gallons, with a sponge filter, sand substrate, and a few Java ferns. Water is at 84°F, pH 6.5, and I do 30% water changes twice a week.

True, and if they're new, they might still be settling in. Sometimes it just takes time. Keep an eye on them, but don't panic yet.

Good call. Let us know if it helps. If not, might be worth a round of general cure just in case. Sometimes they're picky for no obvious reason.
