Guppies, will adapt to full strength seawater, but will not reproduce in it.
As far as adapting mollies(which breed in any salinity!) and flounder to saltwater, replacing freshwater with saltwater as a 50/50 mix adapts them without any ill effects in two days.
This also prevents a possible pH shock.
