A while back, I discovered a way to hatch brine shrimp without a bunch of used pop bottles turned upside down. For a hobbyist, raising a batch or two of egg laying fry doesn't require a large hatchery. I found one that works inside salt or fresh water tanks and provides a more or less constant supply of live baby brine shrimp. It's available from most on-line aquarium supply stores. If I managed to get the right pictures in here, the first one shows angelfish spawning, and the second one shows their fry eating baby brine shrimp directly from the in-tank hatchery. Sorry about the quality of the pictures.
