Beautiful addition to my reef!
The fish arrived in perfect condition. Packaging was triple insulated with heat packs. Acclimation was smooth and it was eating frozen mysis within 2 hours of introduction. AquaEditorial never disappoints.
Great value for the price
Exactly as described. Fast shipping and very well packed.
Good but picky eater
Beautiful specimen, arrived healthy. Takes a while to adjust to new food but eventually started eating pellets. Great addition to my South American cichlid tank.
FAQs
What temperature should I keep the tank at for this fish?
Great question! We recommend maintaining a water temperature of 82–86°F (28–30°C). Discus are tropical fish and thrive in warm, stable water conditions. A reliable heater with a thermostat is essential.
Can I keep this with other fish in a community tank?
Yes! Discus are peaceful and social. They do best with calm tank mates like Cardinal Tetras, Rummy Nose Tetras, and Corydoras Catfish. Avoid aggressive or fast-moving fish that may stress them.
What size tank do I need for a small group?
We recommend a minimum of 55 gallons for a small group of discus. They need spacious aquariums with open swimming areas, live plants, driftwood, and gentle filtration.
What should I feed them?
Discus are omnivores and benefit from a varied diet. We recommend high-quality discus pellets, frozen bloodworms, brine shrimp, and beef heart mixes. A varied diet helps maintain vibrant coloration.
