How many pieces and shapes do you get?

I would say we got maybe 8-10 pieces/20lb box. They are a good size though. It is really neat stuff!

Can it be used in a fresh water aquarium?

Calcium rocks like sea shells in fresh water will leach out calcium and slowly dissolve. Will make you water turn to hard water over time. I would get plastic version if you like the reef rock style.

Does this need to be rinsed and soaked in R/O water before putting in tank?

It should be rinsed, the purpose of buying this rock is to *not* soak it. The coatings on it are meant to soak into the water in the tank to accelerate the adoption of new water to mature it quicker. I have built 3 aquariums with it, and it goes well, but I have had to black them out twice to kill off algae blooms. Bare rock is better if you intend to control all aspects of the maturity. This is a good product imho.
