This guide will provide you with all the information you need to know about keeping and breeding these beautiful fish, from their ideal water parameters to their breeding habits.

The Royal Red Discus: A Fish of Beauty and Grace

The Royal Red Discus is a freshwater fish that is native to the Amazon River basin in South America. It is a member of the cichlid family, and is known for its vibrant red coloration and graceful, flowing fins. Royal Red Discus fish are typically found in slow-moving, heavily planted waters, where they feed on small invertebrates and aquatic plants.

Characteristics of the Royal Red Discus

  • Size: Royal Red Discus can grow to be up to 8 inches in length, although most specimens are typically around 6 inches.
  • Coloration: The Royal Red Discus is known for its vibrant red coloration, which can range from a deep, blood red to a more orange-red. Some specimens may also have blue or green iridescence on their scales.
  • Fins: The Royal Red Discus has long, flowing fins that are often edged in white or blue. The dorsal fin is particularly long and extends all the way to the tail.
  • Temperament: Royal Red Discus are generally peaceful fish, but they can be territorial with other fish of the same species. They are also known to be shy and easily spooked, so it is important to provide them with plenty of hiding places in their aquarium.

Keeping Royal Red Discus: A Guide to Success

Royal Red Discus are relatively easy to care for, but they do have some specific requirements that must be met in order to thrive. Here are some tips for keeping Royal Red Discus successfully:

Water Parameters

  • Temperature: Royal Red Discus prefer warm water, with a temperature range of 82-86 degrees Fahrenheit being ideal.
  • pH: The ideal pH for Royal Red Discus is between 6.0 and 7.0.
  • Hardness: Royal Red Discus prefer soft water, with a hardness of 1-5 dGH being ideal.

Aquarium Size

Royal Red Discus are relatively large fish, so they require a spacious aquarium. A 55-gallon aquarium is the minimum size for a single Royal Red Discus, but a larger aquarium is always better. If you plan on keeping a group of Royal Red Discus, you will need an even larger aquarium.


Royal Red Discus are very sensitive to water quality, so it is important to have a good filtration system in place. A canister filter or a sump filter is a good option for Royal Red Discus aquariums.


Royal Red Discus prefer a fine-grained substrate, such as sand or gravel. The substrate should be kept clean and free of debris.


Royal Red Discus appreciate having plenty of hiding places in their aquarium. You can provide them with hiding places by using driftwood, rocks, and plants. Live plants are also a good option, as they help to keep the water quality high.

Breeding Royal Red Discus: A Rewarding Experience

Breeding Royal Red Discus can be a rewarding experience, but it is also a challenging one. Here are some tips for breeding Royal Red Discus successfully:

Selecting a Breeding Pair

The first step to breeding Royal Red Discus is to select a breeding pair. The best breeding pairs are those that are healthy and have good coloration. You should also choose a pair that is compatible with each other.

Setting Up the Breeding Tank

The breeding tank should be a 10-gallon aquarium that is filled with clean, dechlorinated water. The water should be heated to 84-86 degrees Fahrenheit, and the pH should be between 6.0 and 7.0. You should also add a sponge filter to the breeding tank.


Royal Red Discus typically spawn on a flat surface, such as a piece of slate or a flower pot. The female will lay her eggs on the surface, and the male will fertilize them. The eggs will hatch in about 3-4 days.

Raising the Fry

The fry should be fed live food, such as brine shrimp or daphnia. You can also feed them commercial fry food. The fry will grow quickly, and they will be ready to be sold or traded in about 6 months.
