CRS, CBS and Tiger will cross breed since they are all Caridina. CRS/CBS is selected breed from Bee shrimp, if you cross them with Tiger you may end up Tibee. (Or really low grade CRS/CBS.) Several generation of cross breed you may end up with Pinto than again it takes several generation of cross and select breeding. (assume you made goog color selection.
You can keep 1 Cardina with 1 Neocaridinas . (Crystal red + Red Cherry.) but never 2 Cardina or 2 Neocaridinas. However that doesn't mean both of them will do well as one race will over take another. Water parameter also should aim for CRS/CBS instead RCS.
