General warning be sure to treat for snails from marine warehouse most have pond snails.
Plants are good but some are emerged grown so expect some melting.
As for shrimp they LOVE mosses and riccia as well. Before buying shrimp be sure to know your kh gh and tds from tap. I was using tap and my painted fire reds weren't breeding much however, since I changed to remin rodi they have been quite prolific.
I've found that bristle nose albino plecos do well with my shrimp and have not noticed any missing. Make sure you have a way to acclimate shrimp to the water in your tank and that your tank is 100% cycled before adding them.
As for shrimpers in the area I know only of myself, jeden and dark (over Orlando way).
I started out with ghost shrimp but found they can be quite food aggressive. My pfr are doing well and I've since expanded to two different types crs and some wild types.
Depending on how much moss you're looking for I may be able to help you out if you're interested I should have some anchor moss available when I get to trimming when I have the time.
Do you know what kind of setup you're going for? High tech? Low tech? How much light? I use excel for co2 in my pfe tanks and have no issue, I don't use pressurized co2 in my shrimp tanks because I've seen a lot of topics regarding a lowering in breeding rate on the forums. I use flourish sporadically in my pfr tank and have gradual growth.
Sorry about the book
