I am attempting to breed my own brine shrimp as food for my fish. I took one L of water and one teaspoon of eggs. I aerated it for one hour then used some aquarium salt. I aerated on and off for another 24 hours. One day later, I had about 10000 baby brine shrimp. I fed them a shrimp pellet, and let them be for the night. I got up this am and there are hardly any swimming shrimp left. I have directed a light toward the bottom, which I did this am. What am I doing wrong? Also, since the eggs can't be processed by my fish, how do I separate the live ones from the eggs. Thx
