The Black Moor goldfish, also known as the Broadtail Moor Goldfish, is a telescope-eyed variety of goldfish that, like most other fancy goldfish, is the result of generations upon generations of selective breeding.
The Black Moor has a distinctly velvety black, rounded body with long flowing fins and protruding eyes. They have a single dorsal fin with all other fins being paired. The dorsal fin should be high on the back and the paired caudal fins should have rounded tips. These fish tend to resemble the Veiltail Goldfish.
The telescope eyes of the Black Moor protrude sideways as opposed to the upward protruding eyes of the celestial-eyed goldfish. The eye is on the extreme tip of the telescope part of the eye and due to this, it causes them to have poor eyesight. The Black Moor’s distinctive coloring and protruding eyes do not appear until the fish reaches maturity. Juveniles are often dark bronze in color and have normal looking eyes. As Black Moors grow older they tend to lose their pitch black coloring and start displaying a dark, metallic-bronze coloring on the scales around their belly.
Black Moor temperament and care
Black Moors are one of the more hardy varieties among the fancier breeds of goldfish and are a good option for the novice goldfish enthusiast. However, their eccentric physical characteristics do call for some special considerations.
For starters, the Black Moor is an extremely slow swimmer and thus should not be kept with faster swimming varieties of goldfish, such as the common goldfish, the comet goldfish or shubunkins. Due to their poor eyesight, Black Moors usually take much longer to locate and consume their food, and the faster swimming varieties will often out-compete them for food. Sinking pellet type foods are often preferred for this reason rather than the floating varieties.
The Black Moor’s long, flowing fins are also known to attract the unwanted attentions of common goldfish and comets, which leaves them vulnerable to nipping and bullying. Great care should also be taken when aquascaping and decorating an aquarium with Black Moors. Their protruding eyes are extremely delicate and prone to injury, and any sharp objects or plants with jagged edges should be avoided in the Black Moor aquarium.
Breeding Black Moor goldfish
As with all goldfish, Black Moors can be induced to spawn with proper feeding and a sudden change in water temperature. This is done to mimic the conditions of spring, which is when natural spawning occurs with freshwater fish. As with other goldfish, the Black Moor will readily devour its eggs and fry. So, the serious breeder should use spawning mats or a heavily planted aquarium to provide hiding space for the fry, or remove the parents as soon as the eggs are laid and fertilized.
Choosing Black Moor goldfish
The body depth of an ideal Black Moor should be greater than 2/3 of the body length and the dorsal fin should be roughly 1/3 to 5/8 of the body’s depth. The Black Moor should have a double tail fin and the lobes should be well rounded and forked. The pectoral fins and pelvic fins of a Black Moor should be paired and should be of identical length.
