Chinese algea eating shrimp?

What size , shape and color are amano eggs?
If I remember correctly, black? They do need brackish water to hatch though
 
I just bought 3 the other day and I can only find one. They are pretty neat and expensive. The one we can find molted already.
I'm going to search the internet and see what I can learn about them now.
