I have been breeding central American cichlids and hybrids for a while now and have a situation concerning one of my breeder males. He is proven fertile and has had countless mates and sucessful spawns untill recently. He is paired with a female that he has spawned with b4 and produced fry and now all their eggs are going white they have spawned 3 times since february all no good. I upgraded the wetdry after the 1st fail then after the 2nd i added a uv sterilizer and the eggs she laid on 4/10 are all white now this is slowly driving me crazy
Anyone have idea whats going on
