just googled them, they're pretty cool, unfortunately i also plan on having RCS / BCS and from the posts i was seeing they enjoy shrimp as a staple food =[
you will always hear mixed experiences. I've heard from plenty of people that they are shrimp safe and others say the complete opposite. In the end i think it's up to you to try it and see how the fish react to the shrimp. That's what i will do. Fortunately RCS aren't expensive, they breed prolifically for me and my tank will be heavily planted.
