1) How long had the tank been running before putting shrimp in?
2) Do you have any idea what parameters they came from, is in your tap, or in your tank? Of primary importance is GH, but KH and TDS can play a role as well.
4) If you were to ask most experienced shrimp keepers about Aquatic Arts, you would not get favorable feedback. They are a huge company, and I'm sure some things they do better than others. Sadly, most shrimp are not their strong suit.
Unfortunately, white bodies indicates a bacterial infection, and by the time they are where you can tell they are turning white, it's probably too far gone.
