Goldfish sexing is what most aquarium or fish pond hobbyist would like to know sooner or later. Goldfish breeding is the answer why. As people get more into their hobby they would eventually like to see their fish breed.
Here I am going to tell you and show you the differences between male and female goldfish.
1. Females are generally bigger then the males and are they’re more plump. The reason for this is that there abdomen is all full of eggs when it comes time to breeding.
2. Females abdomen is also more soft and squishy then of the males.
3. They also have rounded and shorter pectoral fins.
4. Females also have a larger rounder anal opening with it slightly protruding as well.
1. Male fish develop breeding tubercles on their gill plates which are most commonly mistaken for the goldfish disease commonly known as Ich. They also get these small white pimple like spots on their outer ridge of their pectoral fins as well. These breeding tubercles appear during spawning time showing they’re ready to breed.
2. Males also have larger longer pectoral fins as well. The pectoral fins are the ones right underneath their gills.
3. They also have a much firmer abdomen then the females.
4. Males have a smaller more oval anal opening then the females.
5. Males are more torpedo shape then females.
These are how to tell the differences between the sexes of male and female goldfish. Here is one of the biggest ways that you can tell as well is when breeding begins to happen you will see the males chasing the females. This is a sure way to tell the differences whether it’s a boy or girl. It’s much the same as real life dating the men usually chase the women 🙂 I will later add some photos of the breeding tubercles of males and pictures of females as well for everyone to see the differences.
