Black Moor Goldfish (Carassius auratus)
The black moor is a telescope-eyed variety of fancy goldfish that has a characteristic pair of protruding eyes. It is also referred to as popeye, telescope, kuro demekin in Japan and dragon-eye in China.
Black Moors (Carassius auratus) have deep bodies and long, flowing finnage, along with characteristic protruding eyes. They are veiltailed and possess metallic scales with a velvet-like appearance.
Young Moors resemble bronze fantails. Their black coloration and eye protrusion develop with age. They can grow up to a length of 10 inches, but may not lose their velvet-like appearance with increasing age. Black demekins may also revert to metallic orange when exposed to warm water temperature. The fish can range in coloring anywhere from a lighter grey to a dark black, but most Black Moor goldfish don't stay pure black forever and many Of them change colors from a rust color underbelly to orange splotches.
Black moor goldfish are popular because they are hardy fish, and because their black color sets them apart from the more common gold color. Goldfish are typically easy to care for, suprisingly, black moors in particular are able to withstand a wide variety of temperatures but cannot withstand extreme temperatures.
Related fish include the entire "telescope" family, and can appear in red, red-and-white, calico, black-and-white, chocolate, brown, blue, bronze, lavender and chocolate-and-blue, tricolored, and black coloration. Black moors with a deep solid black color are difficult to find but are more stable in moors than any other goldfish variety. Black-and-white moors are known as panda moors.
It was once theorised that blackness in goldfish are only exhibited by the telescope-eyed goldfish and that the black colour is only a permanent fixture with telescope eye goldfish. However, with the recent entry of black lionheads (ranchus), black orandas, black pearlscales and black hibunas, this view is no longer true.
In fact, black moors do sometimes throw normal-eye offsprings, and they are black also. However, they are rejected as they do not conformed to the telescope eye feature for the Moor variety.
Black moors have poor vision, therefore mixing them with more active varieties of fish is not recommended. Because of their delicate eyes, an aquarium without any sharp and pointed objects is preferred. If a Black Moor's eyes are damaged, you should quarantine or take the fish to the vet. The Eyes might heal but they will not look as good and most likely be blind. So take caution. They are sensitive to prolonged exposure to low temperature levels. Black moors are very susceptible to dirty water and can die if not kept in very clean water. It is recommended that they be kept with fish with similar sight handicaps, or given more time to get to their food as it could take them so long that they lose out on their meal to other, faster fish in their environment. If kept with other goldfish it will school with them. Black moors will dig in aquarium bottoms, often leading to uprooted plants and decorations. Optimum aquarium environments have a neutral pH and water temperature of 65 to 72°F (18 to 22°C).
Like most goldfish, black moors are prone to overeating, sometimes causing death. These fish should not be overfed.
