The lifespan of the rose crucian carp is about 5 years. Rose crucian carp is an ornamental fish introduced from India. It belongs to the same line of carp as my country's little golden crucian carp. Although the golden crucian carp is bright in color, it is suitable to be kept in the fish tank as an ornamental fish, but the rose crucian carp with good hair color is softer in visual effect, and it looks better with some small aquatic plants.

The requirement for water quality of crucian carp is not high, and the temperature can be stabilized at 22 Above ℃, the pH is as close to neutral as possible, and it is okay to be slightly alkaline. Usually, as long as the water is maintained normally, it will generally not hang up. If it hangs as soon as it is put into the tank, it may be that you have bought sick fish, or have not properly warmed the water. Of course, no matter how well-kept fish are raised, they will die. If you look for problems in your own fish-raising techniques, you should be able to find a reasonable solution. The body shape of the rose crucian carp is affected by many aspects. Wild rose crucian carp can easily exceed 10 cm, while most of them in fish tanks do not exceed 8 cm.
