How to Tell Male and Female Red Crucian Carp Apart? These Identification Methods Are All You Need

There are three ways to tell male and female red crucian carp apart. The first is to look at the body shape: those with a plump belly are female, while those with a slim, elongated body are male;the second is to look at the vent: a wide, flat vent means female, while a small, sunken vent means male;the third is to look at the tail: on a female the body tapers gradually toward the tail, while on a male it suddenly narrows at the vent. For fish of the same size, females have small scales and males have large scales.

Detailed methods for telling male and female red crucian carp apart:

Male and female red crucian carp can be distinguished by looking at the body, the head, the tail, the scales, the vent, the body shape, the genital organs and other features. Generally speaking, female fish of the same age from the same place of origin are always somewhat larger than males.

1. Look at the body: males are long and slender, females are short and wide. The tail also differs: on a female the body tapers gradually toward the tail, while on a male it suddenly narrows at the vent. For fish of the same size, females have small scales and males have large scales. The head also differs: females have a large head and males have a small head, and the male crucian carp's body shape resembles a small carp.

2. Look at the body shape: those with a plump belly are female, while those with a slim, elongated body are male.

3. Look at the vent: a wide, flat vent means female, while a small, sunken vent means male.

4. Look at the nuptial tubercles: those with no nuptial tubercles on the fin rays are female, while those with nuptial tubercles are male.

5. Look at the fin rays: stroke the fin rays with your hand. Those with rough, horny protrusions are male fish, while those that are smooth are female fish. A mature male will release white milt when its belly is gently pressed. Sexually mature and healthy golden carp, golden crucian carp and goldfish can all breed on their own once the breeding season arrives. Look at the gills and the pectoral fins below the gills: those with prominent white spots are male fish, while those without white spots are female fish.

6. Among crucian carp there are generally more females. Females usually have a relatively short but relatively wide body, while males are generally a bit longer and relatively narrow. Judging by the genital pore, females generally have a relatively swollen belly that feels rather soft, with the ribs faintly visible; those whose pectoral fins are fan-shaped are generally female, while those whose pectoral fins are relatively hard and long are generally male. Put some aquatic plants in the tank, and after a while the female will attach her eggs to the plants. There is no need to worry about changing the water, but it is best to change it infrequently and never change more than one third of the water at a time. When changing the water, make sure the temperature difference between the two kinds of water is as small as possible.

The above is an introduction to how to tell male and female red crucian carp apart. I hope it is helpful to everyone.
