Brine Shrimp



I don't know what I am doing wrong. I can get them to hatch great. I want to grow then to adults. I have a tub set up for them. The air filter is low but fast bubbling. I add the nauplii and they do great. But when I feed them for the first time with in 24 hours they die. I feed them Spirlina and yeast. I have tried giving them their first feeding on the first day or second the fifty day. They die. I have tried feeding them just a little to a lot...they die. They do great until that first feeding. Can't be the bubbles because they do great. It only happens after the first feeding. I also try not to put to many together. I do very few. But they die. Yes I have read the ingredients. Nothing else is added to the food. What am I doing wrong!
