with crucian carp? Guppies can't be raised with crucian carp because they are different in habits, body shape and function. First of all, the problem of habits, guppy is a tropical fish, like the water temperature is between 22-26 C, and crucian carp is a cold-water fish, like the water temperature is about 20 C, so it is not suitable for mixed culture.
Next is the size question, the guppy is the small ornamental fish, after the adult approximately in 4-5 centimeters, the crucian carp after the adult body length approximately in 15-20 centimeters. The size difference between the two species is so great that guppies are vulnerable to injury or death if they are mixed together.
Finally, the two kinds of fish have different functions. The nutritional value of crucian carp is relatively high, but the ornamental value is not strong, so most of them are used as food. The guppy is more suitable for viewing because of its bright color and graceful swimming posture. The specific functions of the two kinds of fish are different, so they are not suitable for raising together.
with? Guppies can be raised with some similar and gentle fish, such as colorful angelfish, red and green light fish, Mary fish, zebrafish, red swordfish and so on. Guppies can not only be mixed with fish, but also with snails or aquatic plants. Snails can clean up the garbage on the bottom of the water for them, and aquatic plants can provide oxygen for them.
