You know, when I first started raising fish, it was with guppies. I was told that guppies would give birth faster with live food. I tried with brine shrimp but they were too big. I then bought a packet of brine shrimp eggs and they were small enough to be eaten. I see that everyone is talking about heating the water to hatch the eggs but I just put the eggs in a jar and they hatched with no problem. Also, why do people think that the eggs need heat?
