Who Gives A Fish Forums

I've noticed my discus are less aggressive when I feed them after a water change. Maybe it's the fresh water? My tank is 50 gallons, 5 discus, and I use a HOB filter. Temp at 85F, water changes every 4 days. I also dim the lights during feeding.

If you're gonna ghost-feed, use a pinch of flake every other day. Overdid it once and my nitrates spiked to 50. Had to do a 50% water change. Not fun. What salt mix you running?

I've used dry rock in my 40-gallon and it took forever to cycle, like 8 weeks. But no pests, which was a plus. My Zoanthids finally started spreading after 3 months. Live rock might've sped things up, but I didn't wanna risk hitchhikers.


Yep, dry rock's a slow burn. I dumped in some bottled ...

Agreed on quarantine. Also, avoid anything that nips, like Serpae Tetras. They might seem fine at first, but they can get sketchy. Stick to the chill ones like Corydoras for the bottom. My Sterbai Corys are great with the Discus.


Totally. Corys are a no-brainer. They're active but peaceful, and ...

Yep, health is key. I'd quarantine any new fish for a couple weeks, just to be safe. My last batch of Cardinals had no issues, but better safe than sorry.

I've had good luck with Cardinal Tetras. They're small, colorful, and don't bother the Discus. My tank's similar, 80 gallons, planted with Java Fern and Anubias. Cardinals stick to the middle, while the Discus hang near the bottom. Just make sure you get a school of at least 10 to keep 'em happy.

I've had pairs spawn on a bare bottom, but some prefer a flat surface like a cone or slate. You might wanna toss one in and see if they take to it. What's your plan for raising the fry if they spawn?

Yo, I've had success with a similar setup. Driftwood's a vibe, just make sure it's boiled first to avoid tannins messing with your params. Beef heart's clutch for conditioning, but don't overdo it. How often you gonna do water changes? I do 50% every other day when prepping for spawn.


I agree ...

Re: Has anyone tried to breed Albino Platinums?

Congrats on the spawn Rufus, I'm super jealous lol. Hopefully you'll be raising AP frys soon.

Re: Has anyone tried to breed Albino Platinums?

Wow, Rufus, you're really fortunate to have gotten them to spawn so quickly. I've been waiting for months with my own Albino Platinums and haven't had any luck yet - congratulations are definitely in order. Are the pair in the quarantine tank by ...
