Introduction of the Black Moor Goldfish
Black Moor Goldfish (Carassius auratus) is a beautiful, fancy goldfish variety with solid black color and big, telescope eyes. As they are slow and elegant in movement and social, Black Moors are a popular choice among aquarists who like non-traditional and relaxed fish.
As opposed to some other goldfish, the long eyes and fins of the Black Moor reduce its agility — but that's part of its beauty. They're also tolerant, robust, and ideal for aquariums housing other calm fish.
Origin of the Black Moor Goldfish
Black Moors are an old breed that have been created in China, centuries ago, from the first goldfish. They had telescoping eyes and soft, velvety color, which made them respectful as being good luck and pure beauty in Asian aqua culture. Black Moors are among the most popular and recognized breeds of goldfish today in the world.
Temperament of the Black Moor
Black Moors are peaceful, friendly, and gentle. They only fight or nip on very rare occasions and love swimming slowly about the aquarium. Because of their poor eyesight, they move at a slower pace — so it is best to keep them with other slow-swimming varieties of goldfish such as Fantails, Orandas, or Ryukins.
They enjoy investigating their surroundings and can even identify their masters in time.
Compatibility of the Black Moor Goldfish with Other Fish
Since they are peaceful and calm, suitable tankmates are:
- Fantail Goldfish
- Oranda Goldfish
- Ranchu
- Ryukin
- Bubble Eye Goldfish
Avoid fast or aggressive fish like Comets, Shubunkins, or tropical fish that will outfeed them.
Price Range of the Black Moor Goldfish
Black Moors are inexpensive and easily found. Prices are ₹150–₹400 ($2–$5) based on size and quality of fins. Larger or show-quality fish will be more expensive.
