The following is an observation based on my 9 discus tetras and is by no mean difinative.

I have noticed that the larger of my 9 have a white tip to their anal fin
the smaller fish appear to have a jet black adipose fin.

conclusion
With most tetras the female is larger than the male,
I can only conclude that the ones with white are females and the others are male.
untill a definative study is made of this species by a recognised icthology body.
I will assume that my observations are correct
