Easy-raised aquatic plants
1. Vallisneria angustifolia
Valleya angustifolia is a perennial sessile aquatic plant belonging to the genus Valleya of Eupolyphaga, commonly known as flour grass, Chinese alpine rush and so on. It has stolons, basal leaves and long and narrow leaves, and the length of leaves varies with the depth of water level. The leaves are green, translucent and stand upright in the water. It has strong adaptability to water quality, likes weak alkaline water quality, dislikes high temperature, is cold-resistant and likes light, and often grows in streams and rivers.
2. Crown grass
Crown grass, also known as Amazon sword grass, crown grass and so on It is a large aquatic plant of Alisma of Alismataceae. Its petiole is thick, its leaves are wide and its shape is beautiful. The largest crown grass can grow nearly 100 leaves, the largest of which is 50 cm long and 8 cm wide. Known as the king of aquatic plants, it is suitable for growing in weak acid and neutral water. It likes temperature and light, and the water temperature should be above 24, 26~20.
3. Fine leaf crown
Crown is a small swamp plant, native to Brazil. Its needle-like leaves are 10- 15 cm long and 1 cm wide, with almost no petiole and a total height of about 20 cm. Two or three spiral flowers are about 1.5 cm in size and have six pistils. The leaves are green and solid, the main veins are clear and the veins on both sides are not obvious. By budding, the offspring will grow on the reproductive stem of the mother plant. Like strong light, 20~25 is the best.
4. Mini Crown
The mini-crown originated in Brazil, with a needle-like length of 5~ 15cm and a width of 0.5~ 1cm to adapt to different lighting conditions. Its small size makes it an aquatic plant, which can be arranged at will in the aquarium. It is even better as a foreground grass, and it can be planted in a coarse sand environment. Iron fertilizer needs to be supplemented at any time, and stolons are used for breeding, and the water temperature is 22~27.
5. wave crown
Crown originated in southern Brazil and grew in the waters with slow water flow and low water temperature. The leaves in the water are lanceolate, 25-35 cm long and 2-3 cm wide, and the edges are wavy, so they are called wave grass. There are elliptic aerial leaves, which are15cm long and 9cm wide, and the flowers are about 2cm long. They are propagated by lateral buds on the rhizome. The water temperature is 22~30.
6. Shui Rong
Shui Rong is an aquatic plant of Araceae distributed in West Africa. Compared with other aquatic plants, it is very tough and easy to grow. But if planted at will, the roots will slowly rot and become shorter, and eventually wither. On sunny days, the hardness of water should be slightly higher, the nitrate content should be lower, the bed should have enough base fertilizer, and the suitable growth temperature should be 22~30.

Matters needing attention in cultivating aquatic plants
1. Lighting
Aquaculture needs proper illumination, because only under good illumination can aquatic plants carry out photosynthesis and increase dissolved oxygen in water. If there are many aquatic plants cultured, the dissolved oxygen content in the water will become very low under the condition of insufficient light, and even fish will compete for oxygen, leading to the death of fish due to lack of oxygen.
2. Fertilizer supply
Although aquatic plants can usually absorb fish excrement as nutrients, if there are more aquatic plants and fewer fish, it is better to apply some water and fertilizer if aquatic plants want to grow well.
Step 3 filter water
Whether it is the water for cultivating aquatic plants or fish, it is best to filter it, so that the water quality is clear, the aquatic plants will grow better and better, and the ecosystem in the fish tank will be more perfect.
4. Temperature
Aquaculture of aquatic plants must have a suitable temperature. If the temperature is low, aquatic plants will not grow well, and fish in the water will get sick easily. However, when the temperature is high, the growth of aquatic plants is easily affected. The suitable temperature for aquatic plant culture is generally 24-28 degrees, but it depends on the species of fish and aquatic plants.
Step 5 change water
Generally speaking, fish tanks with aquatic plants don't need to change water frequently, because aquatic plants can purify water, so they can decide to change water according to the actual situation of water quality. When the water quality is slightly turbid, you can consider changing water.
Although aquatic plants have some effects on purifying water quality, this purification effect is mainly reflected in adsorbing some impurities and absorbing some harmful substances. However, not all harmful substances can be removed, and many substances harmful to aquatic animals can also cause harm to aquatic plants.
