Who Gives A Fish Forums

Cloudiness is likely bacterial blooms from overfeeding. Cut back to once daily, and try switching to a mix of pellets and frozen. Also, check your filter flow rate, might need to bump it up if it's under 300 GPH for a 75g.

Fine sand is best—gravel can trap waste and harm their barbels. I use pool filter sand in my tank, easy to clean and looks natural. Just rinse it well before adding.

Avoid resin or painted decor, as they can leach toxins over time. Stick to natural materials like driftwood or smooth river rocks. I've had success with Malaysian driftwood in my 90-gallon, but boil it first to remove tannins. Also, check edges on any rocks—Discus are delicate.

My Discus have developed holes in their heads, and I'm not sure what's causing it. The tank is 75 gallons, kept at 84°F, with a pH of 6.5. I do 30% water changes twice a week, use Seachem Prime, and feed them a mix of frozen bloodworms and pellets. The filter is a Fluval FX6, and the substrate ...

Thanks for the suggestions! I'll start with a group of Cardinals and Sterbai. How many of each would you recommend for a 55 with 6 Discus?

I'm setting up a 55-gallon tank for my Discus and need advice on tankmates. They're about 4 inches, and I've got a sand substrate, planted with Java Fern and Anubias. Water's at 84°F, pH 6.8, with a canister filter. What fish can handle these conditions without stressing them out?

I've only kept captive bred, but they've been great. My 60 gallon's heavily planted, with a canister filter and CO2 injection. I do 40% water changes weekly, and they're thriving. Fed on a mix of pellets and frozen brine shrimp. Heard wild ones need softer water, which I can't provide, so I'm ...

Eheim Jager's reliable for small tanks. Set it to 78-80°F for a Betta. Also, if you're planting, go for a nutrient-rich substrate like Fluval Stratum. It's pricier but worth it.

I've used that tank before. The filter flow is adjustable, so you can tone it down for a Betta. Just make sure to cycle it properly before adding fish. Also, the included light is decent for low-light plants like Anubias.
