Origins and Natural Habitat

The Black Moor Goldfish has a rich history dating back to about 1000 years ago when goldfish were first bred in China. Specifically, the development of Black Moor Goldfish started in the 1400s, which were then traded in Japan, Europe, and America over time. These fascinating fish, known scientifically as “Carassius auratus auratus,” are a type of telescope-eyed goldfish with distinctive black coloration and an egg-shaped body.

As descendants of the Prussian carp – a wild carp species found in North America, Europe, and Asia – your Black Moor Goldfish has its roots in the waters of ancient China. The first incidents of carps being caught and domesticated for ornamental purposes happened in China, and this is where the journey of these elegant fish began.

When it comes to their natural habitat, you’ll find that Black Moor Goldfish thrive in well-maintained aquariums. As a hardy species, they are suitable for both experienced and novice aquarists. Just remember to pay special attention to their bulging eyes, which grow in diameter, providing them with a wider field of vision, an adaptation that makes them unique. Enjoy the company of these captivating fish as you learn more about their origins and care requirements.

Physical Characteristics

Size and Shape

Your Black Moor goldfish will have a rounded body and elegant, flowing fins. They usually grow up to 4 inches in length, although some can reach up to 10 inches in optimal conditions. Their most captivating feature is their unique “dragon eyes,” which are also known as telescope eyes. These bulging eyes grow in diameter due to increased intraocular pressure, allowing for a wider field of vision.

Color and Markings

These charming goldfish are predominantly coal-black in color, hence their name. Occasionally, you may encounter individuals with orange patches that are equally attractive. The solid black coloration all over their bodies is a distinguishing feature and provides a striking contrast to their flowing finnage.

Remember to provide optimal care and a high-quality diet for your Black Moor goldfish, and enjoy their delightful presence in your aquarium or garden pond.

Lifespan and Growth Rate

Black Moor Goldfish have a fairly long lifespan that averages around 10-15 years. With proper care, some can even live up to 20 years! These fish are known to reach a length of 6-8 inches when fully grown, making them a charming addition to your aquarium.

When considering their growth rate, it is essential to note that their telescope eyes grow throughout the first 8 to 24 months of their lives. This growth appears in three shapes: round, conical, and tubular. Round is the most desirable shape since it causes the least difficulty for your fish. On the other hand, the rare tubular shape severely affects their eyesight and coordination.

To ensure a healthy and steady growth rate for your Black Moor Goldfish, provide them with a clean and spacious tank, regular water changes, and a high-quality diet. This way, you can help them reach their full potential and enjoy their unique, captivating presence in your aquarium for many years to come.

Diet and Feeding

As a Black Moor Goldfish owner, it’s essential to provide your fish with a balanced diet to support their wellbeing. A mixture of high-quality flakes or pellets, combined with vegetables, will offer the nutrients they need to thrive. Remember to soak pellets before feeding, as it helps prevent buoyancy issues.

Feed your goldfish in small amounts several times a day, ensuring that the food consumed is moderated to avoid overeating. Black Moor Goldfish may always appear hungry, but resist the temptation to overfeed them. Overfeeding can lead to digestive problems and unhealthy water conditions.

Incorporate live or frozen foods such as brine shrimp, bloodworms, and daphnia into their diet as occasional treats. These protein-rich foods promote growth, enhance color, and improve overall health. However, use these sparingly to prevent an imbalanced diet.

Additionally, blanched veggies like spinach, lettuce, or peas promote easy digestion and provide essential vitamins. Chop these into small, bite-sized pieces for effortless consumption.

Remember that a well-balanced diet contributes significantly to the overall health and longevity of your Black Moor Goldfish, so keep their feeding regiment diverse and controlled for optimal results.

Behavior and Temperament

Black Moor Goldfish are known for their calm and peaceful temperament. They are slow swimmers, making them a great addition to your aquarium or pond, especially if you have other gentle fish species.

Being social creatures, they enjoy the company of other goldfish varieties. However, avoid keeping them with highly competitive tank mates or faster-swimming fish. Due to their protruding eyes and limited vision, Black Moors may struggle to find food amongst more aggressive companions.

By providing them with hiding spots, such as rocks or plants, you’re giving your fish a sense of security and reducing the chances of stress. Maintaining a serene environment further contributes to their well-being as they thrive in tranquil surroundings.

Always pay attention to your Black Moor’s interactions with other fish. If they seem anxious or get picked on, take action to prevent any potential harm. Ensuring a harmonious coexistence enhances the living conditions for all your aquatic inhabitants.

Care and Tank Requirements

Tank Size

To ensure your Black Moor Goldfish thrives, provide them with a spacious tank. For an individual fish, it’s ideal to have at least a 20-30 gallon tank. Keep in mind, with each additional fish, you should add 10-15 gallons.

Water Parameters (Temperature and pH)

Maintaining proper water parameters is crucial for the health of your Black Moor Goldfish. Aim for a stable temperature between 65°F and 72°F. The pH level should be within the 7.0-7.5 range. Regularly monitoring and maintaining these parameters helps keep your fish happy and healthy.

Tank Setup and Decorations

Create an environment that mimics the natural habitat of a goldfish. Opt for a substrate of fine gravel or sand. Provide some aquatic plants and decorations with smooth edges for hiding spots, but ensure that there’s ample space for swimming. Make sure not to overcrowd the tank, as Black Moor Goldfish are known for producing significant waste.

Filtration and Aeration

In addition to maintaining water parameters, it’s essential to invest in a good filtration system. This helps remove excess waste and toxins, maintaining a clean and healthy environment for your fish. Likewise, proper aeration is vital for the Black Moor Goldfish. Consider using an air stone or a bubbler to promote optimal oxygen levels in the water.

Suitable Tank Mates

When selecting tank mates for your Black Moor Goldfish, it’s essential to consider their unique characteristics such as poor eyesight and a slower swimming speed. As a result, you should avoid overcrowding or overstocking their tank to prevent stress and injury.

The most suitable tank mates for Black Moor Goldfish are other medium-sized, peaceful fish. You can comfortably house them with fancy Goldfish breeds, including:

  • Telescopes
  • Veiltails
  • Fringetails
  • Orandas
  • Shubunkins

Aside from Goldfish, you can also introduce Mollies to their tank. Pleco Catfish are popular common algae cleaners found in many Goldfish aquariums—Bristlenose Plecos for smaller tanks and Common Plecos for larger ones. If Plecos don’t fit your needs, consider Glass Catfish and Otocinclus, or Weather Loaches as suitable options.

When considering invertebrates, avoid small aquarium shrimp and snails, as they may become a meal for your Black Moor Goldfish. Instead, opt for larger Apple Snails or Mystery Snails to prevent them from being eaten.

Remember to avoid tropical fish that can’t survive in temperatures below the mid 70°F, single-tailed Goldfish due to their active nature, and fin-nippers like Barbs and Guppies. Additionally, do not introduce aggressive species such as freshwater sharks, Bettas, or Cichlids into the tank.


In summary, caring for your Black Moor goldfish involves maintaining a healthy environment, providing a well-balanced diet, and monitoring their health. With proper care and attention, these fascinating fish can thrive and bring you much joy.

Remember, it’s essential to keep their tank clean, monitor water parameters, and provide adequate space for them to grow. By doing so, you’ll ensure your Black Moor goldfish will have a happy and healthy life. Happy fishkeeping!
