When small piranhas are cultured, diet is the key. Its main diet is mixed feed, but a single mixed feed can not provide all the nutrients needed by the little piranha. Therefore, adding proper amount of aquatic plants, animal protein, vitamins, minerals and other additives to the mixed feed can improve the growth speed and health of the small piranha. In addition, small piranhas also need to eat fresh aquatic plants, small fish, Daphnia, etc. moderately to supplement their protein and nutrients.
2. Water environment
The water environment in which the little piranha lives is very important for its health and growth. Excessive pollution and turbidity of water will affect the growth of small piranhas. Therefore, changing the water source regularly is one of the necessary measures to cultivate small piranhas. When replacing the water source, especially in summer, appropriate amount of bactericide and water quality regulator can be added to ensure the cleanliness and health of the water, thus promoting the growth speed of the little piranha.
3. Activity space
Small piranhas also need plenty of activity space to ensure their health and growth. The breeding environment needs to maintain moderate light and ventilation to avoid overcrowding and overfeeding. Moderately strengthen the exercise of small piranhas, let them swim freely in the water, thus promoting the development of their muscles and organs. At the same time, the water flow and oxygen supply in the water are also essential factors to promote the healthy growth of small piranhas.
4. Experience summary
In the actual culture, it is necessary to sum up experience and keep trying to explore the methods suitable for the growth of small piranhas. For example, cleaning feed residues in time and keeping water clean in daily management are all helpful to promote the growth and development of small piranhas. In addition, regular measurement and observation, timely adjustment of breeding environment and breeding methods can also effectively improve the growth speed and quality of small piranhas.
