I posted to differnt types of food and the way to make it, in the frist part of this tread. There's boiled egg ylk and live brine shrimp. Thos are to really great ways of getting great protain to the fry and helpig to grow faster.
Fish-morger the water temp and water doesn't contral sex of fry the father does, When he fertlizes the eggs he almost predetermans the sex. almost now if yoU let the fry liVe in super bad water i mean super bad water for 6 weeks or more where the reprodutive orgains of the femles can get infected then they will turn into males and beable to sppawn and reproduce fry. But that's only if you neglect the water for weeks at a time.
