I will soon (thanks to Santa ) be setting up a 50 gal planted tank. My red cherries in a 29 gal are happily multiplying (guppies, cardinals, rasboras, sae). I planned on having cory cats, and black mollies as new inhabitants on the 50 gal and want to add some of the cherries.
Should I expect problems from either the black mollies or the cory cats and the shrimp viabilities? The fish in my 29 gal don't seem to bother the shrimp at all.
I once put some juvenile F1 "wild" Poecilia salvatoris mollies into one of my shrimp tanks and they decimated the population despite very dense java moss growth. They would eat the young shrimp and harass the adults to death. They would follow the shrimp into the java moss and harass them out of sight. I don't know if the hybrid mollies offered domestically will react differently, but there is always a possibility that they will act the same.
