Black Moor Fish
History
The Black Moor fish, a fascinating species of goldfish, has a long history dating back to China’s Song Dynasty (960-1279 AD). Goldfish were first domesticated in Chinese ponds for their beauty before being selectively bred, resulting in the birth of several beautiful types, like the Black Moor. This fish is known for its velvety black pigmentation and remarkable telescopic eyes, which rapidly made it a sought-after item among fish fans. The Black Moor’s trip to the West began in the late 17th century, when traders and adventurers brought these exotic fish to Europe, where they quickly became famous in ornamental fishkeeping due to their unique characteristics and ease of maintenance.
- Weight: Black Moor fish typically weigh between 1 to 3 ounces (28 to 85 grams) when fully grown, depending on their size and living conditions.
- Length: These fish can grow up to 6 inches (15 cm) in length, though they are usually smaller in aquariums, often reaching about 4 to 5 inches (10-12 cm).
- Lifespan: With proper care, Black Moor fish can live for 10 to 15 years, though some have been known to live even longer in optimal conditions.
- Coats: The Black Moor’s “coat” is its shiny black scales, which give it a smooth, glistening appearance. These scales can sometimes have a metallic sheen, further enhancing its aesthetic appeal.
- Colors: While their primary color is black, Black Moors can occasionally develop subtle hues of orange or gold, particularly when exposed to sunlight or when their living conditions change.
- Patterns: These fish typically have a solid black color with no distinct patterns, though some may exhibit slight speckling of lighter colors as they age. The unique pattern of bulging eyes is another key feature.
Appearance: What They Look Like
The Black Moor fish is easily identifiable by its glossy black scales, which can range from deep midnight black to a more bluish or brownish hue. These fish have an elongated, round body shape, similar to other goldfish varieties, but with a unique feature – their large, bulging eyes, which protrude outward from their head. This distinct eye shape, combined with their dark color, gives them a charming yet somewhat otherworldly look. Over time, as they mature, some Black Moors may start to develop orange or gold specks, especially if the water conditions are right.
Behavior and Temperament
Black Moor fish are generally peaceful and docile, making them suitable for community aquariums with other non-aggressive species. They are often described as social fish, enjoying the company of other goldfish or similar species. Black Moors are slow swimmers compared to other goldfish varieties, and they tend to stay near the bottom or middle levels of the tank.
Their curious nature and gentle demeanor make them a delight to observe, as they frequently explore their environment and interact with their tankmates. However, due to their large eyes, they may have slightly poorer vision than other fish, which can sometimes affect their ability to compete for food or interact with fast-moving tankmates.
Compatible Tankmates
Black Moor Goldfish are peaceful and slow swimmers, making them ideal for tanks with other non-aggressive fish. They should be kept with species that won’t nip their fins or outcompete them for food. Avoid fast-swimming goldfish like Comets and aggressive fish like Cichlids.

Ideal Living Environment
Black Moor fish thrive in well-maintained freshwater aquariums with ample space to swim and explore. A tank size of at least 20 gallons is recommended for one Black Moor fish, with an additional 10 gallons for each additional fish.
The water temperature should be kept between 65°F and 75°F (18°C to 24°C), with a neutral pH of 7.0. Black Moors prefer calm water with gentle filtration, as their large eyes are more prone to irritation from strong currents. To help them feel secure, it’s important to provide hiding spots such as plants, decorations, or caves. The water quality should be maintained regularly through water changes to prevent the buildup of harmful toxins.
Breeding Black Moor Goldfish
Breeding Black Moor Goldfish requires a well-maintained, separate breeding tank with stable water conditions. To encourage spawning, gradually increase the water temperature to around 75°F (24°C) and provide high-protein foods. Males will chase females, and once eggs are laid, it’s crucial to remove the adults to prevent them from eating the eggs. The eggs hatch in about 5-7 days, and the fry should be fed baby brine shrimp or finely crushed flakes to support healthy growth.
Health Considerations
- Water Quality: Maintain clean, dechlorinated water to prevent diseases like fin rot or velvet disease. Regular water changes are necessary to keep the environment healthy.
- Temperature: Bettas are sensitive to temperature fluctuations. Sudden changes can lead to stress or illness. Using a heater to maintain consistent warmth is important.
- Diet: Betta fish require a high-protein diet, so feed them specialized betta pellets or live/frozen foods like brine shrimp, daphnia, or bloodworms. Overfeeding can lead to obesity or water contamination.
- Tankmates: Bettas are territorial and can become aggressive towards other fish, especially males or other bettas. It is best to house them alone or with peaceful, non-aggressive species.
- Parasites and Infections: Keep an eye out for signs of external parasites, such as white spots (Ich) or skin lesions, which require immediate treatment. Regularly inspect your betta’s fins and body for any signs of damage or infection.
- Stress: Bettas are sensitive to environmental stressors like poor water quality, overcrowding, or a lack of hiding places. Stress can lead to weakened immune systems, making them more susceptible to illness.
Can Black Moor Fish Live with Other Fish?
Yes, Black Moor fish are generally peaceful and can live with other non-aggressive fish, especially other goldfish or calm species like mollies and tetras. However, avoid housing them with fin-nipping fish or aggressive species that might stress or injure them.
Are Black Moor Fish Easy to Keep?
Black Moor fish are relatively easy to care for, but they do require a stable, well-maintained environment. They thrive in clean, oxygen-rich water, so proper filtration and regular water changes are important. They’re a good choice for beginner aquarium enthusiasts, provided their tank is properly set up.
How Big Will Black Moor Fish Get?
Black Moor fish typically grow to about 6-8 inches in length, but in larger tanks or ponds, they can sometimes reach up to 10 inches. Their size can depend on factors such as their environment and how well they are cared for.
What Do Black Moor Fish Symbolize?
Black Moors, like other goldfish, symbolize good luck, wealth, and prosperity in many cultures, particularly in Chinese traditions. Their unique appearance and calm nature also symbolize tranquility and beauty in ornamental fishkeeping.
How to Tell if a Black Moor Fish is Male or Female?
Determining the sex of a Black Moor fish can be tricky, but there are a few signs to look out for:
- Males often develop small white spots (called breeding tubercles) on their gill covers and pectoral fins during the breeding season.
- Females tend to have rounder, fuller bellies, especially when carrying eggs, while males are often slimmer.
