Goldfish. the most popular aquarium fish among fans. For most aquarists, a goldfish becomes the first fish in their aquariums. Unfortunately, the quality of care that they receive in the home aquarium, they occupy far from the first place. While the tropical fish breeding hobby has made great strides in understanding fish needs and improving their care, as well as all other types of aquarium fish, there are still plenty of myths about keeping gold.
Myth 1. A golden fish can live wonderfully in a small round aquarium ball.
One of the most common myths is that a golden fish will be able to live in a small round aquarium. This myth goes back to the distant past, when the breeding of this species has just begun. The first domestic goldfish appeared in China. Then the ancestors of modern carps Koi lived in the nobility ponds, and watched them from above. Over time, goldfish were kept in home aquariums. Bowl-shaped aquariums were the best to observe the fish, but they did not take into account their needs, the preservation of their health and well-being. In fact, this is the worst possible design for the maintenance of aquarium fish. These aquariums are too small, they are very difficult to clean and it is impossible to accommodate the necessary equipment, such as a filter.
Myth 2. Goldfish do not live long
In a sense, this statement is partly true: if a goldfish is incorrectly maintained and cared for, it will not live long. But if it is properly taken care of, to provide her with the necessary home and equipment, she will be able to live up to 20 years and longer. The oldest known domestic goldfish has been living for 43 years.
Myth 3. Goldfish are small and do not require a lot of space.
Goldfish grow very quickly and grow large, and they grow in relation to the environment. A healthy golden fish cannot be small in size, but quite adult it is very large. Even the smallest species reach 16 cm in length in adulthood. Adolescents grow to 3-6 cm, and if the goldfish remains of this size, it means that it was not kept in a sufficiently large aquarium and did not receive sufficient nutrition.
Myth 4. Goldfish are inexpensive and easy to replace.
Goldfish are one of the most common types of aquarium fish, and most of the most common species are relatively inexpensive and readily available. Very many owners treat them like this: if my fish dies, I can easily replace it with a new one. Nevertheless, if this species is provided with proper conditions and care, it can turn into a magnificent aquarium fish, the owner of which can be proud of it. Unusual gold can cost much more than many tropical fish.
Choosing the right aquarium for goldfish
So, we figured out that for a goldfish you need to choose the right rectangular aquarium of the desired size, which can meet their needs. If you want to have only one goldfish, then a 75-liter aquarium will be enough. But if you want more than one individual, then you need an additional at least 30-40 liters, so that you can contain adult fish. Many simply are horrified by the fact that for goldfish you need to have a 200-liter aquarium, but this volume is only the minimum volume for 3-4 individuals! If you want to see this view in all its glory, to fully reveal its potential, you should get an aquarium of at least 330 liters. Remember that these fish grow very large and they produce a large amount of waste, so they need plenty of water. Goldfish live for 20 years and longer, and soon they will become your favorite pets, so do not take the space for them and a spacious aquarium.
Ensure proper aquarium filtration.
Most people do not think about what kind of filter they have in an aquarium with goldfish, and some do not even know that a filter is needed in an aquarium. Filtering in an aquarium with goldfish is needed for the same reasons as for tropical fish, but also because there is so much waste from them. Therefore, for goldfish, ultra-powerful and reliable filtering is necessary. Goldfish love to dig gravel and they absorb a large amount of food, so mechanical and biological filtration is very important. An internal or external filter will do; most importantly, remember that it will need to be cleaned at least once a month so that it can work normally and perform its function of mechanical water purification.
Water changes in the aquarium
Most people know that in a tank you need to do a partial water change, but not everyone knows how often to do it. If you keep a goldfish in a very small, the same round aquarium, then you need to change every day! This is another reason why you should not keep a goldfish in a small aquarium. Even with the maintenance of aquarium fish in sufficient volume, water changes are still necessary. In an aquarium of the correct size, it is necessary to change at least 25% of water once a week. With the help of water replacement you remove waste, ammonia, nitrates, phosphates, and also provide with fresh water a supply of oxygen and nutrients.
Installation of an aquarium
Aquarium for goldfish runs the same way as for other residents of freshwater aquariums. At the bottom should be the soil of the middle fraction, must be stones and snags to provide shelter and resting place for the fish. Daylight should not enter the tank and should be covered with a lid or glass.
The presence of a water heater in an aquarium with goldfish is not at all necessary, for they can withstand very low temperatures, but experienced aquarists advise to acquire it and set it to a low temperature. Although goldfish are capable of living at low water temperatures, they react very poorly to very sudden temperature changes. A water heater will help to avoid this.
Aquarium plants are always a great addition to any aquarium, but we all know that goldfish are simply ruthless. Choose hard-leaved plants such as ferns or anubiasas, and provide about 1 watt of light per liter of water and plants can be quite successful. In addition, plant bushes of softer plants, such as a roach leaf or cabombo, goldfish will gladly pinch them from time to time, but the rest of the plants will be left alone.
Usually, goldfish are kept in an aquarium only with other types of goldfish, because they, unlike all other types of fish, prefer a lower water temperature. Some owners of gold in the same aquarium start small canal catfish, but this type of fish is very large in itself, and when it grows up, it will need its own large aquarium. In principle, goldfish can be mixed with other fish, but exclude too aggressive and overly active species, especially if your goldfish are sluggish veils or syubunkin. Goldfish can get along with both single fish and schooling fish, and even themselves become more active with schools of active neighbors.
These aquarium fish are omnivorous, they can eat both food of animal and plant origin. This means that their diet should contain both protein and vegetable food. Aquarium goldfish are very voracious, they eat constantly. They spend whole days looking for food, so they often need to be fed in small portions. On sale there are many feeds for goldfish, which can become the main, basic feed. Dry food can be fed goldfish several times a day in very small portions so that overeating does not lead to obesity. If a goldfish consumes too much food at one time, it can cause gas and constipation, which can have very serious consequences. Soaking dry food before feeding can help prevent such unwanted effects. In addition, add frozen vegetables, spinach, live aquarium plants, flakes or pellets containing spirulina to the diet. From protein foods: hard-boiled boiled egg yolk, earthworms and shrimp. If your fish has problems with digestion. immediately stop feeding them until the condition improves, and then adjust the diet. Remember that if you feed your fish rarely and in large quantities, the chances of having digestive problems in the fish increase, so feed the goldfish often and in small portions.
Goldfish are often undeservedly accused of a propensity for frequent diseases. In fact, they are quite hardy, and if you create comfortable living conditions for them and properly care for them, then they are much less prone to diseases than any other type of aquarium fish. For the treatment of goldfish from parasites and bacterial infections, you can use the same tools as for the treatment of tropical freshwater fish.
Goldfish is a really great view of aquarium fish. If they are provided with minimum habitat requirements and care, they will be hardy, bright in color and very active. They can be your favorite aquarium pet for many years. So if you have a desire to acquire a goldfish, buy a spacious enough aquarium, provide it with everything you need and properly feed your fish, and you will spend many happy years with your pet.
