Female has to be ripe as it is called and have eggs in her to lay...he is just demonstrating for her right now to encourage ripeness...try this when you do next water change make the water about 2 degrees or so cooler then you normally have the tank. This stimulates the lake during the rainy season and turns the oxygen level in the lake which triggers spawning. The rainy season just ended in Malawi, so lots of breeding will be going on in the lake. I had to do this when I first got all my wild breeders in, and now they are every 30 days or so...good luck Nick-Cichlids In Ohio
As far as the Borleyi goes I have a wild group from Kadango and they are very hard to get to spawn. The male is 4.5-5.0 and has a bright blue face and the reddish body, white tipped dorsal. Females stay the greyish brown with orange fins....so you may have a lot of males if you are seeing tints of blue on the face. Trying to help.....nick
