Shrimphug, When I started I lost 9 tanks of shrimp before I started understanding how to keep them. Don't give up.
The biggest thing I found was to roll with the punches. When I became too serious with them, I became paranoid and tried to do everything by the book. When I relaxed and became more loose, I was able to learn more and observe how things worked. Frustrating? Absolutely. You can always take a break from them until you are ready to try again.
You are already a step ahead of the game. When I started, I knew nothing about forums. Much of my stuff was through trial and error. A forum is a nice place to socialize, but is also great for differing views and a plethora of information to wade through.
