iv'e breed them before it is a pain. % of baby fry that are ebd are a lot weaker and dempsey wiyh only the genes are stronger and more aggressive. you need to make sure to constantly feed the fry newly hatched brin shrimp. after a couple of weeks you will notice if you look close the ebd will look different. the markings on the babys will look marble looking. should seperate fast as possible from other reg dempsey so the have a way better chance of survival.
