identifying the sex of juvenile kribs

Got a pair of juvenile kribs and I'm stumped on the sex. Two males or one male, one female - I just can't tell for sure. Would love to hear your thoughts.

It's tough to sex juvenile fish with certainty. Look for the tail shape - males typically have a more pointed tail, while females have a rounded one.

I'm leaning towards all females, given their age. The rounded fins and the red on the belly are good indicators, and their body shape is starting to take on that characteristic deeper profile. You'll likely have a clearer answer in a few weeks.

The species is Pelvicachromis pulcher, often mistakenly referred to as kribs. If they were Pelvicachromis kribensis, sexing would be relatively easy, as only the females display dorsal spots.
