My male kribensis(pelvicachromis pulcher

This is my male kribensis(called kribby or kribbo...whatever you wish along those lines). Bought him in June, he's spawned approx 7 times, but I only managed to get 2 batches of fry. The 7th batch was the lucky one of all those, and I now have some babies that were hatched in September(30-50)
