Red Head Tapajos sexing

  • We are currently upgrading MFK. thanks! -neo
Color, size, fin shape, length of fin extensions, comparative red in their heads as they mature. Such cues don't apply to all SA cichlids, but they do to Geo t. red heads ime (I bred them). Generally when you raise a group the males will be the larger among them, females a bit smaller. Males for me were generally 6.5-7 3/4 inches, females more like 5-5.5.

Imo, middle fish in the 2nd row of photos is just a little ambiguous, probably female, especially if they're adults, but going on photos alone and not seeing the group in person I'm hesitant to commit 100% to it.

Thanks! That is helpful. The bottom middle was an iffy one when I looked at them as well. Would a video help to better identify if that one is male or female?
