Does a silver molly fish live in salt water or fresh water?

Mollies are one of the few fish that can live in both fresh and salt water. If you are moving a fish from one to the other you should acclimate it slowly by putting the fish in a container and very slowly adding water from the new tank. (Example: Going from fresh to salt you would add a little bit of saltwater to the container with the fish in it regularly until it was mostly salt water after an hour or so.)

Whats the purpose of the salt for platys in a fresh water aquarium?

Salt is commonly added to livebearer tanks because many of the livebearer species were originally collected/discovered in slightly salty water. However, platys are freshwater and don't like salt in the water. Mollies like salt in the water. That's one of the reasons they shouldn't be kept together. (The salt softens the water, to a degree.)
