mcrudd Posted December 19, 2011 Report Share Posted December 19, 2011 Hi there all. I have just over 30 Harlequins in my tank and for the last week or so they have become super active. Chasing each other, spreading their fins and even their colours seem brighter, especially the ones with reddish eyes. I have looked and looked and can't see a very obvious difference with them, so how would I know which are males and females, and has anybody ever had any harlequin fry successfully in an aquarium? Here is a pic of them, not so clear sorry Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 19, 2011 Report Share Posted December 19, 2011 Apparently, you can tell a male from a female by the shape of their marking. The male has a straight front edge that is rounded at the bottom. :dunno: Quote Link to comment Share on other sites More sharing options...
Sophia Posted December 19, 2011 Report Share Posted December 19, 2011 search on Ice222, she has successfully though accidentally bred some copper heads, I think she had a thread about it Quote Link to comment Share on other sites More sharing options...
