100% utterly a guess.... but male on right... female on left....
Its the personalities that make it easier for me to guess male and female so hard to guess from photo... but... that said...
The shape of the ventral fins... narrower and longer is normally a male trait, shorter and wider is normally a female trait...
One on right also looks more curious of camera and seems to be the leader, is ahead and more alert, is chunky and quite... I don't know... broad looking... the one on the left is hanging back, maybe a bit shyer or more submissive, has flatter, narrower face and isn't holding dorsal fin quite so upright...
Hopefully you have a pair there!!
That said, I would add some melafix for a few days, they have right tatty little finnage going on! Typical in young imported angels but being so young and tatty makes them much more prone to bacterial infections... better safe than sorry! If no melafix, if you have any medication with Acriflavin in like Myxazin, a one or two day dose of that will work alternatively...
And they are pretty! And going to get prettier still!! That 'female' already has beautifully dark colouring!
