The Cherries and the Green shrimp are different genus, so in theory they would not cross. The Amanos require salt water in the larvel stage as opposed to the Cherries and Greens benthic lifestyle so there is no danger of them crossing with any of the others. Now if the Cherries and Greens did cross you may get a quite interesting cross. X-Mas shrimp? Then again it's not good to let them cross.
