Male or female discus????

[Trissy1987]

Hi my names Tristan

Recently started keeping discus, I’ve kept the first 3 since November. The other 6 are fairly new over the last month and am trying to find out the best way to tell if I have male or female discus, I have 3 nearly adult discus and 6 juveniles.
I have read that it is virtually impossible. Just wondering if anyone on here had any other information. Thanks for reading 😊

The adults would be predicable but not the little ones. I try to use the dorsal fin prediction. The back of the fin is sometimes pointed for the male while the female is rounder. There are several Youtube videos that will show the examples.

To hard to tell Discus feeding on beefheart or hormone can have long rays.
