Preparing fish tank

Ryukin Goldfish are some of the hardier species of goldfish. They are very undemanding of water quality and temperature. They can do well in goldfish aquariums, a pond, or even a goldfish bowl when small, as long as the environment is safe and their tank mates are not competitive. Setting up an aquarium in a manner that will keep your fish happy and healthy is the first step to successfully fish keeping.

Deciding Aquarium Size

The shape and size of the goldfish aquarium is important and depends upon the number of fish you are going to keep. Goldfish need a lot of oxygen and produce a lot of waste. Keep the tank size and shape in mind when you are buying your fish.

Tank Shape: It is important to give proper fish tank for your Goldfish. For imagery, choose proper goldfish tank that give more space than other. Elongated shaped tank would have more space than tall tank, you should consider this. Always fills your tank to medium limit of water will give more space and oxygen for your goldfish. Surely, much space of your tank is not only will give more oxygen, but this condition will help your water more clean longer, because it will dilute the amount of fish waste and reduce water change frequency.

Tank size: Start with a 20 - 30 gallon tank for your first goldfish is a good idea and then increase the size of the tank by 10 gallons for each additional goldfish. Providing a large amount of water per fish will help dilute the amount of waste and reduce the number of water changes needed.

Water rules: Please keep in mind when you want to buy a new aquarium or fish tank that tank shape and size is important. For proportion only, think that 1 inch of your young goldfish will need 1 gallon of water. As they are growth it will need more space than young fish. With this in mind, you will be more wisely when tailoring what proper size and how many max-numbers of fish in your new tank will give good environment for any aquarium residents.

Fish - size and growth: Refer to tank size and water rule have been described above, you have had imagery now about proper place for your fish. Your goldfish will grow and all things has to you prepare before, include fish tank. The proper environment will improve their growth. First of all, a good reason is to buy fewer fish than the maximum number of fish that can be kept into your tank, because as they grow, they will need more space than they were young, this need you prepared before to keep them at the proper tank size or get a larger tank when they grow mature. Larger gold fish consume much more oxygen than young fish, so if you forget to consider the proper tank size, the environment will dwarf them, goldfish not happy, and can contribute to disease and even death.


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.

Filtration and Temperature

Goldfish produce a lot of waste. Good filtration, especially biological filtration, is very helpful in maintaining the water quality of the aquarium. Filtration systems remove much of the detritus, excess foods and waste. This helps keep the tank clean and maintain 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) with ph: 6.0 to 8.0. Unlike the flat-bodied types of goldfish, the Ryukin has a lower tolerance for pollution and cannot tolerate temperatures much below 60° F (16° C).

Aquarium Decor and Substrate

Would you use tank ornamentation? But make sure all ornamentation you have placed is smooth and no sharp object. Because some goldfish sensitive with sharp object (e.g. Bubble Eye goldfish and Celestial Eye Goldfish). They will have very vulnerable eyes sac. So that, give drift wood, smooth rocks, water plant (either live or plastic) is more safe way to decor your aquarium.
Water Change

Regular weekly water changes of 1/4 to 1/3 is strongly recommended to keep these fish healthy. Snails can be added as they reduce the algae in the tank, helping to keep it clean.
