This is a discussion on how many for my tank within the Invertebrates forums, part of the Freshwater and Tropical Fish category; -->

They will surely be eaten by the mollies, especially in such a small tank. Perhaps if the mollies were in an appropriately sized tank, the shrimp would have a shot at being able to sustain a colony. You would need to start with a decent number to give them a foothold.
