Why does my tropical fish always hang up? How long does it take for the dried water? Can't you replace them all at once? Can you put aquatic plants in the fish tank? Urgent!

1, water quality problem! The pH value of water quality should be between 6.4 and 6.8. The hardness should be between 4.4 and 4.8.

2, filtration system! Add nitrifying bacteria for large-flow out-of-cylinder filtration or upward filtration! Don't forget to add filter cotton!

3. change the water! Be sure to expose the water for a day or two before changing it, because there is chlorine in tap water, which is not good! Change the water by a third or a quarter every week! If you change it all at once, it will basically belong to a new environment. Small fish have a process of adaptation, and poor physique will die!

4, the problem of oxygenation! The fish tank should always be kept in an oxygen-rich state! Otherwise the fish will die, too!

5, the problem of raising aquatic plants! It is better to raise aquatic plants in fish tanks, but there are many problems when raising aquatic plants. Root fertilizer, base fertilizer, liquid fertilizer, light and carbon dioxide should all be considered!

If you are a novice, it is not recommended to raise aquatic plants immediately. Let's raise the fish first! If you really want to raise aquatic plants, the above conditions must be met. If you don't understand, you can send me a message!
