With the overall improvement in people's living standards, hobbies have become more diverse. Among these, keeping goldfish has gained immense popularity. Known as the "Oriental Holy Fish," goldfish are cherished for their unique shapes, vibrant colors, and graceful swimming movements. More and more people are choosing to keep one or two lively and adorable goldfish at home. Not only do they enhance the aesthetic appeal of a living space, but they also help regulate indoor temperature and humidity, creating a more comfortable environment.
Here is a detailed guide on how to properly care for and manage goldfish indoors:
First, water quality is essential. While goldfish can adapt to various water conditions, it’s best to use clean, chlorine-free water. Tap water is commonly used, but chlorine must be removed before use. The simplest way is to let the tap water sit for 24 hours to allow the chlorine to evaporate, making it safe for the fish.
Second, water temperature plays a crucial role. Goldfish are cold-blooded animals, so their body temperature matches the surrounding water. They can survive in temperatures ranging from 0°C to 39°C, but sudden temperature changes can cause stress or even death. When introducing new fish, place the plastic bag in the aquarium for 10–20 minutes to equalize the temperature before releasing the fish.
Third, dissolved oxygen levels should be maintained above 4 mg/L. Aeration devices or filter pumps can help ensure adequate oxygenation, which improves appetite, keeps the water fresh, and reduces disease risk.
Fourth, stocking density should be carefully managed. Overcrowding can lead to poor health and even death. In a standard 60 cm x 30 cm x 35 cm tank, 5–6 adult goldfish can be kept. If an aerator is used, the number can be increased by 1–2 times.
Fifth, regular water changes are necessary. In summer, change about 1/3 to 1/4 of the water daily, and clean the tank every 3–4 days to maintain hygiene.
Sixth, feeding practices should be consistent. Goldfish are omnivores and can eat live food like brine shrimp or dried feeds. Feed them once or twice a day, depending on the water temperature. Observe the feces to determine if they're being overfed or underfed.
Seventh, disease prevention is key. Regularly disinfect the tank with potassium permanganate or salt solutions. Maintaining clean water and proper oxygen levels can significantly reduce the risk of illness.
Finally, breeding goldfish requires careful preparation. Select healthy, mature fish and provide optimal conditions for spawning. After eggs are laid, move them to a separate hatching tank to increase survival rates. Proper management during this period ensures successful reproduction and healthy fry.
By following these guidelines, goldfish enthusiasts can enjoy the beauty and tranquility that these elegant creatures bring into their homes.
