OK, I am thinking about breeding brine shrimp for some fry (guppy). Upon reasearching most of the sites tell that brine shrimp live and breed in salt water. So now I'm confused. If brine shrimp are used as food for freshwater, but are bred in saltwater, how is this possible? Are they like, dual watered? Help would be cool. I have always fed my guppie fry on powdered tetra/guppy flakes but am wanting to try something new, should I just drop it and continue what I am doing?
