An Introduction to the Powder Blue Discus

The powder blue discus is a stunning freshwater fish that is highly sought after in the aquarium trade. With their bright blue coloration and graceful movements, powder blue discus make an eye-catching addition to planted aquariums. In this article, we'll take a deep dive into everything you need to know about keeping and caring for these beautiful fish.

The Origins of the Powder Blue Discus

Discus fish originate from the Amazon River basin in South America. There are several natural color variations of discus that have been bred in captivity, including the vibrant powder blue. Powder blue discus are thought to be a color morph of the blue discus, which is found around the Rio Negro region of the Amazon.

The first powder blue discus were likely bred by aquarists in the 1980s or 1990s. Breeders selectively mated blue discus that showed a lighter, powdery blue coloration. Over generations of selective breeding, the powder blue color morph was established.

Today, most powder blue discus are commercially bred on fish farms in Southeast Asia. Captive breeding has allowed powder blue discus to become more readily available in the aquarium trade.

The Appearance of Powder Blue Discus

As their name suggests, powder blue discus display a striking blue color over much of their body. The main body color ranges from a pale sky blue to a deeper robin's egg blue. The fins are a complementing transparent blue.

Powder blue discus typically have a series of horizontal brown bars running along their sides. These bars can range from very faint to more pronounced. Some specimens may also have scattered white spots across the body.

These fish have a compressed, disc-shaped body like other discus species. Adults usually reach 5 to 7 inches in diameter in captivity. Powder blue discus have oval shaped faces and dorsal and anal fins that come to rounded points.

Powder Blue Discus Care Guidelines

Despite their delicate beauty, powder blue discus are not beginner fish. They require pristine water conditions, frequent feedings, and warm water. With good care, powder blue discus can live around 5 to 10 years in an aquarium.

Here are some key care guidelines for keeping healthy, thriving powder blue discus fish:

• Tank Size - A minimum of 55 gallons, though larger is ideal.
• Water Temperature - 82°F to 86°F.
• pH - Between 6.0 to 7.0.
• Water Hardness - Very soft, 2 to 6 dGH.
• Filtration - Strong external canister filter.
• Feeding - 2 to 5 small meals per day. Quality frozen, live, and pelleted foods.
• Tankmates - Peaceful community fish. Avoid aggressive species.
• Plants - Broad leaf plants like Amazon sword. Driftwood and rocks.

Performing partial water changes of 30% weekly is crucial for powder blue discus care as well. Their water needs to be pristine to avoid health issues.

Feeding Powder Blue Discus Fish

Powder blue discus need to be fed small, frequent meals 2 to 5 times daily. Make sure not to overfeed, as these fish are sensitive to deteriorating water conditions.

A high quality staple diet is essential. Feed a mixture of frozen foods like blood worms and brine shrimp along with granules and flakes. Live foods like black worms, daphnia, and glass worms can also be fed occasionally.

Soak dry foods before feeding to prevent bloating. Vary the diet by rotating different frozen, live, and prepared foods for optimal nutrition.

Breeding Powder Blue Discus

Experienced aquarists can try breeding powder blue discus. They reach sexual maturity around 12 to 18 months and can be bred in pairs or small groups.

To induce spawning, perform large water changes using soft, warm water. Feed live and frozen foods high in protein. Set up a separate bare bottom breeding tank with slightly acidic water between 82°F to 86°F.

During spawning, the pair will clean a flat surface like a piece of slate. About 100 to 300 eggs are laid and quickly fertilized. Remove the parents after spawning is complete.

The eggs will hatch in 24 to 36 hours. Feed the tiny fry infusoria and powdered fry foods 5 to 6 times per day. Perform frequent water changes to support growth. In 3 to 4 months the juvenile discus will begin to display their adult coloration.

Finding Healthy Powder Blue Discus

When shopping for powder blue discus, look for specimens housed in their own tank at the store, not with other discus varieties. This reduces the chance of cross-breeding.

Select active fish with clear eyes, full bellies, and vivid blue coloring. The skin should be free of lesions or white spots. Make sure the discus you choose are fully grown, around 5 inches in diameter.

Ask when and where the fish were imported from. Powder blue discus bred locally tend to adapt better. Always quarantine new arrivals for at least 2 to 4 weeks before adding them to an established aquarium.
