Its a female in the pictures

Rounded red belly and a spade shaped tail. Males tend to have the red colour round their thoats too and a pointed tail :)

I’ll repeat it here for the benefit of others....
Female kribensis have short rounded ventral fins, that don’t go more than half way to the anal fin. Males have long pointed anal fins that reach to the anal fin. They can be sexed easily by this characteristic from 1” long. It’s the reason why the genus Pelvicachromis was created, and applies to all members of the genus.

Other methods can be unreliable. Some males have bright red bellies, and some are the same shape as females. The tail shape only comes in with sexual maturity...
