Fish Folk Posted December 4, 2021 Share Posted December 4, 2021 I’ve always heard / read / been told that the only sure-fire way to sex discus short of pulling them out and comparing tubes under a magnifying glass is to wait until they pair off. But as I’ve been watching mine mature, there’s definitely some that are growing a noticeably pointy dorsal, while others are curved. Has anyone used this as a reliable clue when sexing discus before? I’m still a newb to these gorgeous fish… Link to comment Share on other sites More sharing options...
MoshJosh Posted December 5, 2021 Share Posted December 5, 2021 As far as I know only way to sex discuss is watching the female lay eggs or the method you mentioned above. 1 Link to comment Share on other sites More sharing options...
