yes. And i see somed people who post in red cherry who hace crystal reds or cardinas. i think the sub fourms should be renamed to neocardina and cardina respectfully. they are completely different setups. i would argue that neos is the preferred choice since most people wont have a RO filter in their house, or will want to buy RO water at the store just for their fish tank.It also depends on what type of shrimp you want to keep as some have different needs.
