No they do not "need" salt in their water. Mollies (Poecilia sp.) originally came from brackish (Estuarine) waters and provided it is done very slowly they can eventully live in a marine environment, but they have been kept and bred in fresh water for so long now that salt is not a neccessity as it once was 60 years ago.

Why marine fish die when placed in fresh water aquarium?
They're designed for salt water, not fresh water! Just the way they are made. You can get aquarium salt from your local pet store, but don't put any in there if you have other freshwater fish that don't need it. Or get a tropical freshwater fish like mollies instead!
Can a fourteen ghost shrimp live in a one gallon tank with two dalmatian mollies and a chinese algae eater?
No. Your tank is ridiculously overstocked. Your algae eater will eventually grow to the size of 12 inches long. Your mollies need more space. And your shrimp will soon die because of the polluted water from the overcrowded conditions.
What do mollies need to thrive in a freshwater aquarium?
Like any other fish Mollies need good conditions. Ample room, (1"of fish=1Gal water+ 6sq" surface area) ample food and water parameters to suit them are not hard to provide. They are essentially algae eaters but also like a bit of live food too. Comming from warm brackish waters a temp around 70F and a little salt added (1tsp per Gal) would be appreciated.
