Need Help Sexing Discus Fish

[whereskob]

Hi, I'd love some help sexing my discus, I think there both males but I'd love a pro opinion. I just bought the striped one today and the other is being slightly aggressive, mainly following the other around and generally just annoying him

Thanks for your help!

It's really difficult to sex discus, especially without seeing their behavior. Have they paired off at all yet?

I'd say the white is female and the striped is male due to the shape of the dorsal fin.

Hi Kelly-Jo

IMO they are too young to be able to sex them correctly. How big are they? They look to be quite young fish to me.
