Electric blue ram

[F15HHH]

Hello there!
I recently purchased a couple of electric blue ram very young from shop and they couldn’t tell me if they were male or female. I’ve attached the photo I’ve managed to get if someone could help me sex them ?
Thanks in advance

They’re not the easiest fish to sex. For me the small one is too young. The big one is female. It has large eyes which means it’s older than it’s size would suggest, and if it was male it would have a much taller, more vertical forehead.
