How many fish should you keep at home?

Read the above answers. If you have a silver dragon in your tank, I will tell you that even one is not enough. Your fish tank is too small. I have raised a silver dragon for several years. If the tank is too small, it will affect the growth of the silver dragon. If you raise it properly, it will grow to about 40-50cm in one year. After a year and a half, it will not fall in your tank at all. In the end, the body shape will become ugly. If you must keep a silver dragon, it is recommended to keep only one, and it is better to mix it with a parrot. I still recommend changing to a larger tank. Finally, arowanas are not kept in even numbers, but in odd numbers.
