Hello i have a male Melanochromis johanni and i have it in a tank with 2 other yellow chilids and 2 other cichlids. I am not sure what kind of fish they are and i was wondering if they are by chance female Melanochromis johanni. If they are could someone pls inform me on how to breed these amazing fish. They are very shy also and if anyone knows why and how to fix this pls tell me. They are in a 15 gallon tank I will include a picture below.
