The Black Moor fish, known scientifically as Carassius auratus auratus, is a captivating and distinctive variety of goldfish that has captured the hearts of fish enthusiasts around the world. With its unique appearance and graceful swimming style, the Black Moor fish has become a popular choice for aquarium hobbyists. In this article, we will explore the remarkable features, care requirements, and interesting facts about the Black Moor fish.

Appearance and Characteristics

The Black Moor fish is instantly recognizable for its striking appearance. It has a rounded, egg-shaped body with a characteristic pair of protruding eyes that are large and telescope-like. The eyes, which may be black or metallic in color, give the fish a distinctive and almost comical appearance. The body of the Black Moor fish is typically dark, ranging from deep black to a velvety charcoal color. Its scales have a velvety texture, adding to its unique charm.

Size and Lifespan:

When properly cared for, Black Moor fish can grow up to 6 inches (15 cm) in length. However, their growth rate tends to be slower compared to other goldfish varieties. With good care and a suitable environment, these fish can live for 10 to 15 years or even longer, making them a long-term commitment for fish enthusiasts.

Habitat and Tank Requirements:

Black Moor fish are native to China and were selectively bred for their striking coloration. When it comes to their habitat, they thrive in well-maintained freshwater aquariums. It is essential to provide them with a tank that is spacious enough to accommodate their growth and swimming needs. A minimum tank size of 20 gallons is recommended for a single Black Moor fish, with an additional 10 gallons per additional fish.

Water conditions are crucial for the health of the Black Moor fish. The water should be kept clean, well-filtered, and free from harmful chemicals. Regular water changes and monitoring of ammonia, nitrite, and nitrate levels are necessary to maintain optimal water quality.

Diet and Feeding:

Black Moor fish are omnivorous and have a hearty appetite. They enjoy a varied diet that includes high-quality commercial flakes or pellets, supplemented with live or frozen foods such as brine shrimp, daphnia, and bloodworms. It is essential to feed them in small portions multiple times a day to prevent overfeeding and maintain their health.

Social Behavior:

Black Moor fish are generally peaceful and can coexist with other goldfish varieties, as well as other peaceful community fish. However, it is crucial to ensure that tank mates are compatible in terms of size and temperament to prevent any aggression or stress. Providing hiding places and ample swimming space is essential for the well-being of these fish.

Breeding:

Breeding Black Moor fish can be a challenging endeavor due to their specific requirements. The process typically involves simulating seasonal changes and providing suitable breeding conditions, including appropriate temperature, water quality, and spawning sites. The breeding process often takes place in a separate breeding tank to protect the eggs and fry from potential predation.


The Black Moor fish is a captivating and beautiful addition to any freshwater aquarium. With its distinct appearance, graceful swimming style, and relatively easy care requirements, it has become a favorite among aquarists. By providing a spacious tank, clean water, a balanced diet, and suitable tank mates, fish enthusiasts can enjoy the elegance and charm of the Black Moor fish for many years. So, if you're looking for a stunning aquatic beauty to enhance your aquarium, the Black Moor fish is an excellent choice that will bring joy and wonder to your aquatic world.
