The Black Moor Goldfish will do well in a 30 gallon or larger tank with a fine gravel bottom and hardy, cold water plants. Goldfish are diggers and will scatter the fine sand onto leaves, injuring thin and less hardy plants. Roots and well-rounded river rocks are appreciated.

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. They should be fed small pieces of live or prepared foods designed for egg-laying fish.

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.
