Temperature: Maintain the water temperature between 68°F and 74°F (20°C to 23°C).

pH Level: Maintain a pH range of 6.5 to 7.5.

Water Hardness: Ideally, keep the water hardness between 5 and 12 dGH (degrees of General Hardness).

Tank Size and Setup:

Tank Size: Provide a spacious aquarium with a minimum capacity of 20 gallons for a single Black Oranda. For multiple Black Orandas, increase the tank size accordingly.

Filtration: Install a reliable filtration system to maintain water quality and remove impurities.

Decorations: Black Orandas appreciate a well-decorated tank with live or artificial plants, driftwood, and smooth rocks. These elements create hiding places and simulate a natural environment.

Lighting: Moderate lighting is suitable for the Black Oranda fish, but avoid excessive direct sunlight.

Compatible Tank Mates:

While the Black Oranda is generally peaceful, it is important to select tank mates that will not harm or stress this delicate fish. Compatible tank mates include:

Other goldfish varieties like Ryukin, Ranchu, or Telescope.

Non-aggressive coldwater fish such as White Cloud Mountain Minnows or Bristlenose Plecos.

Avoid housing Black Orandas with fin-nipping or aggressive species, as this can cause stress and damage their flowing fins.

Feeding Habits and Diet:

Black Oranda fish are omnivorous and have a hearty appetite. Feed them a balanced diet to maintain their health and vibrant coloration. Here are some feeding guidelines:

High-quality Pellets or Flakes: Offer a staple diet of high-quality goldfish pellets or flakes formulated specifically for fancy goldfish.

Supplemental Foods: Enhance their diet with occasional treats like bloodworms, brine shrimp, daphnia, or chopped vegetables such as peas.

Feeding Frequency: Feed your Black Oranda fish 2-3 times a day in small portions, ensuring they consume the food within a few minutes. Avoid overfeeding to prevent digestive issues.

General Care and Maintenance:

To provide the best care for your Black Oranda fish, consider the following tips:

Regular Water Changes: Perform regular partial water changes (around 20%) weekly to maintain water quality and remove excess waste.

Monitoring Ammonia and Nitrite Levels: Regularly test the aquarium water to ensure ammonia and nitrite levels are at zero, as these can be harmful to fish.

Observation and Health Checks: Observe your Black Orandas regularly to detect any signs of illness, such as changes in behavior, loss of appetite, or abnormal growths. Consult a veterinarian specializing in aquatic animals if needed.

Maintain a Stable Environment: Avoid drastic temperature or pH fluctuations, as these can stress the fish and compromise their health.
