There are generally two reasons why aquatic plants rot, one is that the water quality in the tank is not good, and the other is that they are not bought with aquatic plants. Raising aquatic plants is different from raising fish. The water body should be acidic, but the ph should not be too low. At the same time, attention should be paid to the water temperature. Anything entering the tank should be disinfected, otherwise it will lead to the decay of aquatic plants. In addition, you must buy ready-made aquatic plants, and never buy aquatic plant seeds. Most of the so-called aquatic plant seeds are terrestrial plants, which will naturally rot when raised in water.

1. Moss: Moss aquatic plants are one of the most common aquatic plants, which belong to negative aquatic plants, have low demand for light and are easy to raise. It is a bryophyte, which needs to be fixed on Stone or sunken wood because it has no roots. It is very suitable for landscape and can absorb waste from water as its own nutrients.

2. Ficus microcarpa: Ficus microcarpa is an emergent herb native to West Africa. Its height is about 10-15 cm, and it can grow freely in bright places without light. It likes warm environment and is afraid of low temperature. Therefore, if planted artificially, the temperature should be controlled between 22-30 ℃, and it should not be lower than 15 ℃ in winter.

3. Iron crown: Iron crown is a fern widely distributed in southern China, and can grow in water in rainy season. This kind of plant grows very fast, and it can be cut and reproduced, so it can easily cover the bottom of the tank and become a good scene.
