Yeah, mollies are quite adaptable. We breed sailfins to feed to new arrivals that are picky feeders at the aquarium until we can get them feeding on prepared foods. We raise them in both brackish and full freshwater, and have kept them in full saltwater before also. They breed best in brackish, but we've had babies in all salinity levels. I have thrown many-a-mollie from freshwater (~150 ppm TDS, pH 6.8) directly into saltwater (30+ppt, pH 8.3) with no obvious signs of acclimation stress, at least for those that don't get eaten immediately that is .
