Black comet Goldfish can be called Black Bubble Eye goldfish also!

Origins and Habitat

The Black Moor Goldfish results from selective fish breeding from China and Japan used to receive and retain its defining genetic abnormality – telescope eyes. This was achieved by confining such fish eyes into just a single pond giving rise to dozens of smaller spawns. This unique black color and long body fins were then fixed into permanence.


The blackmoor goldfish is relatively easy to identify among other species of Goldfish. Black moors can reach 6-8 inches (15-20 cm). They will also grow very round and take on an egg-like shape which slows their movements through the water.

Blackmoor tank requirements

The black moor makes wastes very much and can very quickly pollute up the tank water. For this type of Goldfish, the recommended minimum tanks are 100 gallons (380L).

Goldfish will require a balanced diet consisting of good quality protein and vegetable matter and sinking pellets, flakes, or gel foods high in protein and fiber. Healthy vegetable treats such as beans should be available sometimes as store-bought products should not be the prime source of nutritional content. It is possible to reduce the protein percentage as young adults develop, but high fiber and protein should remain consistent for maximum digestion. The fiber levels should be uniform.

Blackmoor diet

Similar to any goldfish, black moors are omnivore fish, with a tendency to be herbivores. So, to ensure an adequate diet for your fish, you need to include plants and animal-origin feds. Fish flakes should also contain frozen foods like worms, shrimp, daphnia, and tubifex worms. Round-bodied Goldfish are highly susceptible to swimming bladder issues, and good nutrition can help prevent digestive problems. When frozen and dry foods are consumed, they should always be soaked into tank water before being offered. This aids your animals in digesting it and can stop them from suffering constipation.

Diet and feeding

Green vegetables are good for support the digestive system. Lettuce, spinach, and broccoli are some examples that work well. Feed Black Moor Goldfish as often as you can, but in small amounts.

Tankmates for Black Moor Goldfish

Black Moors move slowly with their long eyes, so they can not get as quickly into food as other goldfish species do. A small number of goldfish species can be somewhat aggressive and have a ‘butt head’ to compete for food. Goldfish with a similar temperament should not be allowed to go into one aquarium. Suggested companions are also telescope or bubble vision kinds. Most aquarists like to keep at least two Black Moorors together as a single kind of fancy goldfish fish tank.

Black Moor Goldfish in communities

Are Black Moors good tankmates?

Black Moors are prone to form good friends when housed and kept appropriately. Unfortunately, they don’t make good community tanks mates with several different kinds of fish. They should ideally be kept with other slow-moving similar-size fancy Goldfish in appropriately decorated and maintained tanks. Keep them relatively equal in size and slow-moving so as not to bully anyone. Make sure to get enough swimming space for every fish in the tank.


In the wild, the spawning season is usually in spring, so all it takes is making sure your condition mimics that of the wild. The females lay their eggs on roots and mops, so ensure there should be plenty of this type of spawn substrate. On average, each pair can hatch 10,000 eggs – and that could occur within two days. When the larvae hatch, feed them a packed diet for the first two months. Eventually, you can re-inject them to parents and offer them similar food. You know the magic will begin when you see your precious Goldfish flying around each other.

Breeding black moors

Like all goldfish varieties, black moor begins laying eggs when water temperatures rise. The female Blackmoor lays her eggs, and then the male fertilizes them. Spawning could take several hours, and a female fish can lay over 10000 eggs at a time. About a week after they hatch their egg, the fry can freely swim. They feed small, high iron, and high protein foods until fry becomes big enough to eat similar foods to their parents. Once that period (approx two months) is over, you should be able to place these in your pond.

Breeding your Black Moor Goldfish: For Fun and Profit

Hardiness and Diseases

The black moor has a solid and determined disposition. If you maintain your water parameters stable and the water quality, this species won’t develop any trouble. They look delicate at once, though. Sometimes they can tagle in your aquarium net or end up hit by an object. They can also suffer from a urinary system infection. Sometimes it can happen to your black moors to be debilitated by velvet diseases. Please be careful whenever you notice spots or change the color; this is tricky because this change of color is natural and forms part of the species’ growth, and can indicate a disease.

Take care

You should have no trouble with your Goldfish. Because they are delicate, they may need more attention than other types of goldfish. All their organs are squashed in their small body and can increase their chances of illness. Skin diseases like velvet disease are generally the case in Goldfish and are caused by parasites and bacteria. If you see an infected fish, move them to quarantine tanks to prevent this bacteria from growing on other fish. Make sure you watch their eyes while moving. In the case of keeping the tank, clean problems should be less frequent. This includes weekly water changes for maintaining excellent water quality.
