Help! How to distinguish between male and female Tropheus duboisi?

To distinguish between male and female Tropheus duboisi, you can look at the genital area. Tropheus duboisi males have two holes of the same size, while female fish only have two holes of different sizes; the large size is for the release of eggs, and the small size is the anus.

Meanwhile, the characteristics of male Tropheus duboisi fish show faster growth, with longer pelvic fins and a more pronounced head bump. In contrast, females are smaller in development and rounder in shape.
