If you are talking specifically about the freshwater varieties, I haven't tried to acclimate them to seawater.
In your case I'd keep them in mostly fresh water with a stable pH, and especially with high oxygen and low ammonia. Some folks tend to neglect food holding tanks, but they are fairly easy to keep clean with normal husbandry.
Any power filter with strainer will work fine for filtration/water movement and oxygenation, but you can also use an air pump with a big sponge filter (or both) for good biological filtration.
