    Hi,

    I recently saw a nice picture on how to sex juvenile fish from the nijsseni complex (from mike wise)
    Does this exist for regani complex?

    I have a lot of 2 month old Ortegai juveniles and was wondering on when I would be able to determine their gender.

    Kind regards,
    Matthias

    Not that I know about. If they show no differences then they are too young. Behavior might be an indicator, but not always.

    Hi Mike,

    Thanks for your reply!

    They indeed show differences.
    I can see that most of the fish have a thick black border in their pelvic fins, a lot more than even my adult males have. So i'm quite sure these are females.
    They also show more black in the first 3 spines of their dorsal fin.
    Also less spaces in the blacks on the bottom of their dorsal fin.

    I think I have around 3 males and 7 females but they are only 2 cm so I will wait a little bit longer to be sure.
    Sorry that not all pics are as sharp as they should be :)
