Is this apisto hongsloi a female?

I'm sorry for posting yet another gender identification question.

After failing to find a male panduro I decided to go for a pair of apisto hongsloi.

The male is obvious but the female coloured up straight after being added to the tank... and I think it's a male as there's some red showing up on the body and fins.

Can someone confirm? If it is indeed a male what is a failsafe way of picking a female at the store (as opposed to a subdominant male).

Pretty sure it's a male. Females of A. hongsloi stay smaller usually.
