Keeping livebearers is simple and easy to deal with aggressive males. Either keep all males (there will be a bit of squabble but nothing serious) or keep 2 females to every male in the tank. The mollies can handle freshwater but you must acclimate them to whatever condition you are changing to. If they were bought from a fw tank, then a cpl hrs of drip will do. To change them to sw will take much more time slowly increasing the salinity (sg) over the course of many weeks. Brackish will be somewhere in the middle. Remember, just adding aquarium salt will NOT make a tank brackish.
