this site is also very helpful in the actual process of hatching them out. I have not allowed them to grow to full size brine, I feed them at the baby size but there is info on there about growing them. I just simply use the water from my saltwater tank in the dish. They prefer salinity of 1.024 to .028 I then have a goldfish bowl that I place the hatched shrimp in with a airstone dialed down with more water from the tank that I allow to continue to grow for about 12 hours so they can get to the next stage. After that point, I will add supplements, selco directly to the water and let them eat that for an additional 12-18 hours. By that time they are ready to be fed. The whole process is like 2 days. Make sure you rinse the final product out prior to feeding them to your fish or sea horse using a brine shrimp net or sieve. But it really is easy once you get a system set up. I have also bought some petri dishes so I can cold store them in the fridge so I can have a supply on hand. They can be stored that way for a couple days, and simply take them out and warm them up under the lights
