Common mistakes and suggestions in goldfish care

Goldfish are among the most preferred fish species by aquarium lovers around the world, with their eye-catching colors, elegant movements and unique beauty. Caring for these beautiful creatures can be a little more complicated than other pets, and frequent mistakes can unfortunately seriously affect your goldfish's health. Although these mistakes are often made with good intentions, without fully understanding or considering the fish's needs, the consequences can be serious. In this article, you can find tips on what these frequently made mistakes are and how to prevent them.

Choose an aquarium large enough for your fish

Goldfish are active and mobile fish that can generally reach quite large sizes, and they generally need an aquarium of at least 40-75 liters. The general rule is to increase the size of the aquarium by approximately 40 liters for each additional goldfish.

An inadequate size of the aquarium restricts the goldfish's movements, which negatively affects the physical development of the fish and causes it to experience additional stress. Stress increases aggression, especially among fish living together, or weakens immunity, making your fish vulnerable to diseases.

In addition, it is more difficult to control water quality in a small aquarium. Since goldfish can quickly pollute the water, nitrate, nitrite and ammonia levels can rise rapidly in a small aquarium, poisoning the fish, causing health problems, and even shortening their lifespan.

Use a water purifying filter in the aquarium

Using a filter in the goldfish aquarium is very important to maintain the quality of the aquarium water. The aquarium filter cleans the water in three different ways: mechanical, chemical and biological. Mechanical filtration removes solid waste from water. Chemical filtration helps maintain the chemical balance of water. Biological filtration, on the other hand, converts harmful ammonia and nitrites in water into less harmful nitrates. These three filtering processes together ensure that the overall quality of the water remains high.

Not using a filter in the aquarium causes the water quality to deteriorate rapidly. Fish experience serious respiratory problems and health problems. In the long term, this can significantly shorten the fish's lifespan. Additionally, it is necessary to change the water more frequently in an aquarium without a filter. This requires more labor and creates extra stress for the fish.
