How to tell if your goldfish is male or female

This is the only guide you’ll ever need to determine whether your goldfish is a male or female. Keep in mind that none of these characteristics will 100% determine the sex, but if you look for multiple characteristics and see them in the same fish, you can usually be correct. The most effective way however is to look for what they produce at breeding season, that will tell you for a fact. #fish #goldfish #aquarium #goldfishbreeding
