Can aquatic plants be put directly in the fish tank after they are bought?

Reason: The newly bought aquatic plants may have pathogenic effects on the raised fish. When fish get sick, it will affect more fish and cause a large number of fish to die. Most aquatic plants are wash-free. When adding water directly into the tank, it is best to spread a film on the grass mud to avoid directly impacting the grass when adding water, otherwise it may be turbid. Some fish will eat these aquatic plants, which is not conducive to the reproduction of aquatic plants. Aquatic plants are dirty when bought, so they should be cleaned, otherwise the fish tank will not look good when put in.

Placing aquatic plants in a shallow water basin, and irradiating with a 8W- 15W ultraviolet lamp at a distance of about 15-20cm for 5-15min, and turning the aquatic plants upside down for 5-15min; Exposure to the hot sun will have the same effect.

Under the light, aquatic plants constantly inject oxygen into the water and into the bottom. Frankly speaking, no artificial equipment can accomplish the same function. In the aquarium, oxygen is released in the form of water, but it is visible in some cases, for example, tiny oxygen bubbles may rise from damaged leaves to the water surface, and the importance of oxygen in the aquarium.
