Yes--babies are much easier. Here's a quick and dirty brine shrip hatchery. all you need is a 1 qt Chinese souop takeout container, a rigid airline and some tubing, and an air pump. And some brine shrimp eggs. (www.seahorsesource.com has them).
So you fill the container with fresh new saltwater, add some eggs. Make a small hole in the container lid, enough to fit your airline through. Put the cover on your container, put the airline through to the bottom, hook it up to the airpump. Plug it in. Wait a day.
(the jar is just to keep them in motion--and if you like you can add some powdered spirulina or yeast to gut load the baby brine.
Ahhhh yes sea horses very tricky .... you must add vitamins before feeding brine also try to get them to eat frozen mysis shrimp. When they get bigger you can through in ghost shrimp. They are very picky and you have to watch them every feeding
