You really are going to need better photos to be sure.
The first photo of the Sen appears female from the anal fin and the stomach line.
The second photo of the Sen the anal fin has the meaty appearance of a male. (though females can have this too, but not so common)
But the length of the fin in the second shot appears female.
So tricky one that without a clearer photo.
As for the Delhezi, again pictures are not really helping much but at this point I would sway towards female.
