Many people want to know if the goldfish they keep is male or female. Maybe you want to determine this for breeding purposes or just to name your fish the right sex for it. Fortunately, you can determine whether the fish you are keeping is male or female based on its physical characteristics and behavioral signs.
Steps
Identify female fish
- Females also have a larger dorsal-to-belly distance, making it easier to determine the sex of the fish when viewed from the side.
- As the spawning season approaches, eggs will begin to develop in the female’s body; this can cause one side of the fish’s body to swell and appear asymmetrical, or one side to sag. [1] X Research Source
- When viewed from the side, the female’s vent may appear to be a protrusion from the fish’s abdomen.
- In addition to the protruding vent sign, females also have thicker anal fins than males. [2] X Research Source
Identify male fish
- Usually the spawning nodules will only appear during the spawning season of the fish. However, for older males that have lived through several breeding seasons, the nodules can be present year-round.
- The nodules may also appear on the pectoral fins, on the face or on the fish scales.
- Note that although the appearance of nodules is a reliable sign that a goldfish is male, a fish without the nodules is not necessarily a female, as it is not a female. Every male fish has nodules. [3] X Research Sources
- The male goldfish will chase the female around the tank or aquarium, swimming close behind and slightly lower than the female, sometimes ramming the female’s tail.
- The male fish will also try to force the female into the tank wall or into the plants in the tank to force the female to lay eggs.
- However, male goldfish also chase each other around even without the female, so you should observe their body stats and behavior to determine their sex. [4] X Research Sources
Understand the difficulties
- However, the maturity level of goldfish will depend on species and sex. For some fish breeds, the male will reach adulthood at 9 months of age, while for some females it can take up to 3 years to mature.
- Without the use of DNA analysis, it is practically impossible to determine the sex of the goldfish. If you want to increase your chances of having both male and female fish, it is best to buy at least 6 healthy fish of the same breed. According to statistics, the probability of having at least one fish of the opposite sex with the rest is 98%. [4] X Research Sources
- Some male goldfish do not develop nodules. On the contrary, in rare cases, female fish have these nodules. Some females do not have a protruding vent, but sometimes males do.
- Additionally, some varieties of goldfish do not follow this rule – for example, some varieties of goldfish (such as ranchu or ryukin) have naturally thick round bodies that make sex determination by their shape. fish is impossible.

- For the above reasons, it is best to sex your goldfish by observing multiple signs rather than relying on just one.
- For example, an unhealthy male goldfish may not develop nodules during the breeding season, while an unhealthy female may not have a protrusion.
- The shape of the fish can also be confusing. A thin goldfish may be mistaken for a male (as males are usually smaller), but it is possible that it is a malnourished female. On the other hand, you may think that the fish has a bloated belly, but that is a sign of edema (a type of internal bacterial infection). [4] X Research Sources
Advice
- Some goldfish enthusiasts also believe that males are generally lighter in color and more active than females.
- Try going to aquarium stores to see larger goldfish. This can help you learn to tell them apart more easily.
