The Common Goldfish is a member of the goldfish group, long-time favourites of many beginner hobbyists. The Goldfish derived its common name from its golden scale.
similar to an oranda variety. The Goldfish is found in a variety of colours, including red, orange, black, and white, and is almost always a combination of colours. The Goldfish will do best in a tank with a fine gravel bottom and hardy, cold water plants.
It is a digger, 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. Courtship culminates in up to 1,000 eggs, with fry hatching in five to six days.
Fry should be fed small live food, and until about 8 months of age, have a very unimpressive, drab coloration.
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.
