So, I'm wondering how feeding live brine shrimp works. You get them in a little bag with water. The directions say to rinse them in fresh water before putting into the tank. Are brine shrimp salt or fresh-water creatures? How long would they survive in a tank if uneaten by the fish? One probably won't throw the whole batch in at once - how long would they survive in a jar? Someone once suggested to keep them in the fridge, which would slow down their demise. The fridge?!
