Who Gives A Fish Forums

Flakes are a no-go for my group too. They're picky eaters, so I stick to frozen brine shrimp and Omega One pellets. Tank's a 90-gallon with a sump, and I keep the pH at 6.5 with peat in the filter. Lighting's on for eight hours a day, and I've got some floating plants to dim it a bit.

I've had success with a mix of live and powdered food. Fry in a 50-gallon, temp at 86°F, with a HOB filter. Water changes 40% daily. They're active and growing well. What's your tank's pH?

Room temp's 68F here, and my Discus are chill with two Aqueon Pro 150Ws. Key is to match heater wattage to tank size—rule of thumb is 5W per gallon. OP, you're underpowered with a single 300W in 75 gallons.

I've kept Emperor Tetras for years, and I always drip acclimate. They're pretty hardy, but why risk it? Takes like 30 minutes tops. My tank's similar to yours, 75°F, pH 7.0, and they've been thriving.


Agreed. I've seen fish go into shock from quick acclimation. Not worth the gamble. My tank's ...

Sounds like typical Discus behavior, especially if they're establishing a pecking order. At 4 inches, they're hitting maturity, and dominance battles are common. Your params look solid, but I'd bump water changes to 30% twice a week to reduce stress. Also, try adding more hiding spots—maybe some ...

My Discus have been chasing each other nonstop for the past week. Tank is 75 gallons, temp at 84°F, pH 6.8, 0 ammonia, 0 nitrite, 10 nitrate. They're around 4 inches, fed twice daily with frozen bloodworms and beef heart mix. Tankmates are 6 Cardinal Tetras and a pair of Rams. Filter is a Fluval 407 ...

Re: How to

Thanks for the advice. Same tap water for both tanks, and I do 50% water changes twice a week on both.

Re: How to

Just had a thought - I've got a 125 gallon tank with a couple of Oscars, been running for 6 months with 4 Aqua clear filters. There's plenty of foam media I could take from that tank. I was thinking the media should come from the same tank as the discus, but is that really necessary?

Re: How to

I'd say start with a small amount, maybe 1/4 cup of the ceramic bio pieces, see how it goes.

Re: How to

I was thinking of moving them in a few days. The tank they're in has a decent amount of gravel, about an inch. Moving some of that over could also help, right?
