Here are three tricks for raising undead fish:
1.Control water temperature: Aquarium fish need the right water temperature to survive, for example, goldfish need water temperature between 15 -28, tropical fish need water temperature between 25 -28, koi need water temperature between 20 -28, and arowana need water temperature between 25 -28. High-quality equipment such as Weber's high-precision heating rods can help you stabilize the water temperature and avoid fish diseases caused by water temperature fluctuations.
2.Water quality control: Fish farming requires water to be raised and a nitrification system to be established. The new tank needs to be cycled and oxygenated for 3-7 days to establish nitrifying bacteria in the tank. The frequency of water change is 5-7 days, change one-fifth to one-third each time, pay attention to the water temperature fluctuation should not exceed 1, and clean the filter cotton regularly to ensure water quality.
3.Ensure water quality and nutrition: For example, the lactic acid bacteria in yogurt are aerobic resistant anaerobic bacteria that can survive for 3 to 5 days in an oxygen-rich environment, so using yogurt in the fish tank can increase the number of nitrifying bacteria, but be careful not to overuse it, otherwise it may spoil the water quality.
The above are three tricks for raising fish and undead fish, I hope it will help you.
