without an oxygen pump. It is very dangerous to raise small goldfish without an oxygen pump. If the number of goldfish is relatively small and the tank is relatively large, there will be no problem. But if the number of goldfish is relatively large, it is dangerous, because goldfish themselves are highly oxygen-consuming fish, in the absence of oxygen, they can only live for a few days. If there is an extreme lack of oxygen in the tank, they may not survive for a day.
when raising small goldfish do not put oxygen pump, as long as pay attention to the following points is no problem.
1. Space: It is better to choose a slightly larger fish tank when raising. The larger the fish tank, the more water it contains, and the more dissolved oxygen it contains. In addition, the mouth of the fish tank should be larger, which can increase the contact surface between water and air, which is conducive to their breathing.
2. Food: Breeders should follow the principle of eating less when feeding food. Each feeding should ensure that they can eat within five minutes. Try not to feed food at night.
3. Water quality: Keep the water clean and change the water frequently to ensure sufficient dissolved oxygen in the water.
