Patrick_G Posted June 30, 2022 Share Posted June 30, 2022 I had a trio of swordtails but the male died. The only surviving fry from their first batch in my tank was female. Recently she decided to grow a sword and gonopodium. Sorry about the out of focus pic, He never stops moving! He gets a to keep his old name “Glen Fry” 😁 Link to comment Share on other sites More sharing options...
Cinnebuns Posted June 30, 2022 Share Posted June 30, 2022 How old was the fry? How confident are you it was female? I don't know much about swordtails specifically but I know in guppies there are often males who are late bloomers. Could this be the case? I've been told some fish can change their sex but idk what species can or cannot Link to comment Share on other sites More sharing options...
