can discus eat live blackworms?

Post by gleek2 »

I've been thinking about adding live blackworms to my Discus diet. They're in a 75-gallon tank with sand substrate, driftwood, and a few Amazon swords. Water's at 84°F, pH 6.5, and I do 30% water changes twice a week. Anyone got experience with this?

Yep, blackworms are a solid choice. I've fed them to my Discus for years in a 120-gallon planted tank. Key is sourcing from a clean supplier. I use a small feeding dish to keep the worms contained. Just make sure your filtration can handle the extra waste.

Sounds sketchy to me. My buddy's Discus got bloated after eating live worms. Maybe stick to frozen bloodworms? I run a canister filter on my 55-gallon, and even those mess with the water quality if I overdo it.

Agreed. I've had success with blackworms too, but quarantine them first. My Discus are in a 90-gallon with a sponge filter and weekly 50% water changes. No issues so far.

Live blackworms are nutrient-dense, but risky if not handled right. I culture my own in a separate tank to avoid parasites. My Discus are in a 100-gallon with CO2 injection and LED lighting. They've thrived on a mix of blackworms, pellets, and occasional beef heart.

I'm new to Discus, so this is helpful. My tank's only 40 gallons with a hang-on-back filter. Maybe I'll try frozen first. How often do you feed live worms?

Culturing your own is smart. I feed live blackworms twice a week in my 65-gallon. Tank's got a UV sterilizer just in case. Discus go nuts for them.

My Discus are picky. They'll eat flakes and pellets but ignore live food. Maybe I'll try blackworms next. Tank's a 50-gallon with a sponge filter and java fern. Water's at 82°F, pH 6.8.

Blackworms are great, but don't overdo it. I feed them once a week in my 180-gallon. Tank's got a sump, and I monitor nitrates closely. Discus are healthy, but variety's key. I rotate between worms, brine shrimp, and high-quality pellets.

Thanks for the advice, everyone. Gonna start with a small batch and see how they react. Appreciate the tips on sourcing and quarantine.
