"The Black Moor Goldfish is one of several varieties of Carassius auratus auratus. Goldfish originally came from parts of Asia, Japan, and China but now enjoy worldwide distribution thanks to controlled breeding programs. The Black Moor Goldfish is of the Veil Tail variety, and has an overall black coloration. Moor varieties have metallic scales. All goldfish are members of the carp group and are generally quite hardy.
There appears to be a definite courtship ritual when Goldfish breed. Breeding often results in up to 1,000 eggs, with fry hatching in five to six days. Goldfish are omnivorous, and will eat all types of dried and live foods. Limit protein, however, to 30% of the diet. A Goldfish flake or pellet food will provide these fish with the proper nutrition.
