Goldfish can live indefinitely without an air pump if the tank is properly oxygenated through other means, such as surface water movement or live plants.
However, the absence of an air pump requires careful management of the tank environment to ensure adequate oxygen levels are maintained. Anyway, in our previous article, we told you how long can goldfish live without a filter, so if you are interested you can read this article.
Goldfish require oxygen to breathe, and in a tank without an air pump, oxygen can be supplied by ensuring a large surface area of water is exposed to air, which facilitates gas exchange.
Additionally, the presence of live plants can help oxygenate the water through photosynthesis. The key to keeping goldfish healthy without an air pump lies in maintaining clean water, avoiding overcrowding, and ensuring the tank setup supports natural oxygenation processes.
It’s essential to monitor water quality and oxygen levels closely, especially in tanks without mechanical aeration. Regular water changes and proper tank management can prevent the buildup of toxins and support a healthy oxygen level.
While goldfish can survive without an air pump, their health and activity levels can be better supported with adequate oxygenation strategies, ensuring they lead long and healthy lives.
