The oranda is a very deep bodied goldfish, and his perfect body depth should not be less than 2/3 of its length, not including the tail. He can grow to a rather large size of up to 12 inches, which makes him one of the larger breed of goldfish. He has a long quadruple tail, and comes in many colors including red, red/white, red/black, black, blue, chocolate or bronze, white, calico, panda (black/white), tricolor (red/black/white), redcap (white body/red wen), and his scales can be either matte or shiny.

Setting up a goldfish aquarium in a manner that will keep your fish happy and healthy is the first step to success. The shape and size of the aquarium is important and depends upon the number of goldfish you are going to keep. These fish need a lot of oxygen and produce a lot of waste. Good filtration, especially biological filtration, is very helpful in maintaining the water quality of the aquarium. A filtration system will remove much of the detritus, excess foods, and waste, which keeps the tank clean and maintains the general health of the goldfish.Goldfish are a cold water fish and will do best at temperatures between 65 - 72° F (18°- 22° C). Unlike the flat-bodied types of goldfish however, the Lionhead Goldfish have a lower tolerance for pollution and cannot tolerate temperatures much below 60° F (16° C).Provide a gravel substrate to help create a natural and comfortable environment for your fish. You can add some decor, but make sure that all ornamentation is smooth with no protruding points or sharp edges. Smooth rocks or driftwood should be used sparingly if at all. Aquarium plants would be the best choice of aquarium decor for goldfish, but unfortunately these fish are diggers. Consequently live plants may be uprooted. Artificial plants make a good substitute and silk plants are safer than plastic ones.Most aquariums come with a cover that includes lighting. A cover for the tank is desirable as it reduces evaporation and though they are not prone to jumping, on occasion some gold fish will jump out. Lighting is not essential for goldfish, but does make the aquarium a nice show piece and lighting will help if you have live plants.Goldfish are freshwater fish, but they have some tolerance for slightly brackish water. The salinity level for must be kept low, below 10% with a specific gravity of less than 1.002. Jump to Minimum tank size - If your Oranda Goldfish are in an aquarium that is ..

You should at least provide a 20 gallon fish tank, minimum for your Oranda goldfish and as the goldfish grows increase the tank size. This tank should be larger if you want to have more than one fish.Since The Orients first developed goldfish from carp, these fascinating fish have expanded to include a variety of colors, shapes, and sizes. Some common goldfish types are even bred to develop special characteristics. Bulging eyes, raspberry-like head growths, eyes that gaze heaven-ward, round fluid-filled eye sacks, elaborate nostrils, and flowing fins to name a few.Get coffee bean sized gravel for the bottom of the Oranda goldfish tank (if it is any smaller, the goldfish could accidentally swallow some while feeding and die). Make sure any rocks or gravel are metal-free, since rocks with metals can harm fish by becoming toxic residues into the surrounding water.I have two very small goldfish and two red caps(medium size 2 inch) in a 10 gallon tank with a good filter. I do water changes once a week or so. There’s a bubbler in the tank and a few decorations. Do you think this set up is fine?The Oranda Goldfish are actually easy to breed, but only during the breeding season. Otherwise, it is a very difficult task. The male and the female can be distinguished by their body size. The male fish is more slender and smaller, compared to the female Oranda Goldfish. During the breeding period, the male fish display many white dots all over the head. These white dots are known as ‘breeding tubercles’, and is often mistaken to be suffering from ich disease. They undergo many courtship rituals, like the male fish chasing the female, touching or nudging the belly of the female and encouraging her to lay eggs. The low-temperature period, which is followed by increasing temperature at a slower pace, induces these fish to spawn. The female Oranda can lay more than 1000 eggs in a single spawn, but a very few percentage of eggs survives. As soon as the female fish lays eggs, the male fish fertilizes the eggs by spraying a substance called “milt” from their body. It takes around 5 to 6 days for the eggs to hatch. These small fry should be provided small pieces of prepared foods or live foods, usually given to the egg-laying female fish.The oranda goldfish is among the most popular aquarium fish in the world. Orandas are available in two color varieties — metallic and calico-based. The metallic oranda goldfish, as its name suggests, has a distinctive sheen and can be purchased in many different colors. The calico-based variety have a bluish-tone and are covered in spots. Sex can be determined by comparing the size and features of the the fish in your tank. If you do not have multiple orandas, the sex can only be determined by examining the fish closely when the water is warm enough to encourage breeding.
