Guess many different ways to do this. I’m hatching in this.7A1AD953-7CA4-4D80-A041-2297AF6B7FF3.jpg. They hatch in around 24hrs and seem to live for about 3 days. Right now I’ve got 2 of those hatched. Tomorrow I will try to refrigerate some. The shrimp go to where I aim the light. The shells seem to float to the top shrimp under.
