CJs Aquatics Posted May 19, 2023 Share Posted May 19, 2023 Grabbed some images from online they do not belong to me but I was hoping someone can help me learn to identify goldfish genders as I’m considering getting some: Link to comment Share on other sites More sharing options...
SunBearQ Posted May 19, 2023 Share Posted May 19, 2023 I am no expert but I have found the easiest way to sex goldfish is whether they have breeding stars/tubercles on their gill plates and pectoral fins. Adult males have them and females do not. With regards to venting, females protrude and males do not. Based on your photos I am guessing: 1. M, 2. F, 3. F, 4. M, 5. M, 6. F Females are also rounder in shape and are chased by the males relentlessly during breeding. There are videos on YouTube that can better elaborate my Cliff Notes explanation. Hope this helps. 1 Link to comment Share on other sites More sharing options...
