I wouldn't relate your ghost shrimp experience to that of dwarf shrimp such as RCS, yellows, etc. which are much easier to keep alive IMO than ghost shrimp. Ghost shrimp are generally sold as feeders and that's why they are so cheap. They are often sick and diseased as well. I purchased 24 of them back in September or October and have maybe 6 of them alive still and that includes one that I raised from the larval stage. All of my RCS, yellows, and snowball shrimp are THRIVING. They eat algae and pellet food for the most part and ghost shrimp are more of a detritus feeder and scavenger but I still give them some flake once in a while. Overall, I don't see why you need "experience" if you are wanting some of the Neocaridina species of dwarf shrimp like RCS since they are extremely hardy. Expensive crystal red shrimp (high grades) on the other hand I wouldn't recommend getting right away. You'd be better off getting less expensive CRS (The lowest grade, C-grade, sell for about $3 each). The higher grades such as the ones I have were on average $14 each. It really sucks losing those!
