Ap. Borellii Opal - male and female?

[Daniel Hultqvist]

Hi experts out there!

I just got a pair of these. Can you please confirm that they are in fact a male and a female Ap Borellii Opal?

Here are two pictures of them.

They are rather small still, and pictures are crappy.
Hope you can help me anyway.

Size? If small (1"/3,5 cm) SL, then probably too small/young to sex.

About 4 cm I guess.
I think this one is a female. Not sure about the other.

Not sure about the other. But it looks like the others' dorsal fin is longer.

I agree, this fish appears to be a female A. borellii.

Looks like fin tips have been nibbled off, so fin length won't be useful until they have time to grow back.
Lighting from the front might help, to show the blue iridescence on the cheeks better; males should have more.
