Category: Gold Fish
Very popular in both the US and Japan, the Ryukin goldfish has a very big dorsal hump. Ryukin goldfish origin: from Japan. It is named after a string of Islands between Japan and Taiwan. It was bred in Japan from Fantail goldfish family somewhere in the late 1700s. Red and White Ryukins goldfish are very common in the US
Ryukins are fairly aggressive and will bully weaker breeds (like the Celestials and Bubble Eyes goldfish) for food. So they should only be kept with other Ryukins or fish of similar swimming capability, such as Orandas and Lionheads.
Usually, when goldfish float upside down it is a symptom of swim bladder disorder. But with Ryukins, it is a common sign of constipation. Overfeeding is the usually the reason for this. Goldfish do not have stomachs, so you must feed them in little portions several times a day
Letting the Ryukins eat foods like pealed green peas will be a good laxitive. But another answer to the problem is to simply stop feeding the fish for a few days until the fishes digestive tract clears out.
You can put the goldfish in a pond, but they were bred to be viewed from the side, so they were intended for aquariums. Ryukins goldfish do not tolerate cold water as well as the Common Goldfish.
You need to provided the proper filtering. Ryukin Goldfish create a lot of waste and are known for being messy. Your filter should completely clean the water at least ten times an hour. If there is a twenty gallon tank, you will need a filter that can handle the waste of at least 200 gallons per hour. A filter that cleans more than ten times the amount of water in your fish tank is more than adequate.
Get coffee bean sized gravel for the bottom of the Ryukins 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 becomming toxic residues into the surrounding water.
To decorate your tank, Buy some ornaments and decorations and fake plants. Do not buy ornaments with openings small enough that the fish can get stuck in them! Remember to consider how large your goldfish can get. When choosing decorations you should add plants; goldfish will nibble on some live ones, usually tough plants such as hornwort, vals, anubias, and tere are others that are fine.
Cycling your tank is important, Follow the steps to cycle your tank. This establishes healthy bacterial and chemical levels.
When buying your Red Ryukins goldfish see which ones look like the healthier ones in the tank. Be wary of tanks with dead fish in them, this can be a sign of illness or improper care. In addition, healthy fish will: Have no white spots, swim with their fins held upright, Have a nice rich color or colors. Not be afraid of people, Swim around all over the fish tank and look healthy. Clamped fins are a sign of sickness
Adding the Red Ryukins gold fish to your tank: It is important to introduce the fish to the tank environment slowly. As soon as you get home, float the entire closed pet store bag on the top of your fish tank (with the Red Ryukins goldfish inside!) for about a half hour. This will allow the water in the plastic bag and the fish tank water to equal out and the bag to become the same temperature as your tank water. Next thing to do is, add a small amount of water from your tank to the bag, and wait about 15 minutes. Do this at least one more time. Dispose of the water down a drain from the bag. Then, use a net to transfer the Red Ryukins goldfish fish carefully into the your tank. Dispose of all of the water in the bag. This process not only reduces stress for you fish, it also prevents the dirty pet store water from contaminating your fish tank.
Goldfish Diet: Omnivore. Feed the Red Ryukins goldfish three times a day in small portions, gold fish do not have stomachs, that's why small portions more times a day will prevent wasted food. Feed a good quality goldfish food, pellets or flakes. Ryukins may also eat frozen foods such as brine shrimp, bloodworms, and krill. Also, you can feed them vegetables like peas, leafy greens like collards and kale. Cut or tear them up into small pieces for the gold fish. Temperature: prefer water in the range of 65.0 to 72.0� F (18.3 to 22.2� C). Care Level: Easy for a novice Test the water. Preparing your tank: minimum tank size 30 gallons. Read up on the nitrogen cycle in aquariums for goldfish. You will need to purchase a liquid test so that you can test for Nitrates and Ammonia. The strip-style test kits are unreliable and a waste of money. You should use a dechlorinating product to remove the harmful chlorine from the water. Test for nitrite, ammonia, and proper PH. The ammonia should always be 0, the nitrite should be 0, and the nitrate should be below 20. If it's at or above 40, you have too many fish or are not changing the water often enough! If there is ammonia or nitrite, your tank is still cycling and you need to do your research about the cycling process.
Doing weekly water changes, once a week, remove and replace 30%-50% of the water in Ryukins goldfish tank. Removing all the water from the tank will damage the bacteria that has grown that helps decompose the fish waste. Make sure to dechlorinate the new water before adding it to the tank.
Perform a thorough gravel cleaning once every 2 weeks or so. you need to use a gravel vac which vacs up debris while removing water. With tropical aquariums, it is often recommended that you do this once a month, but with goldfish (who produce an absurd amount of waste)you will need to do this as frequently as you can. Once a week is recommended.
