I think you mean tap water. Tap water or pipe water as it is sometimes called sometimes has in too much chlorine. But tropical fish are still fresh water fishes. What I have heard some people do is before they introduce their pet fishes to a aquarium they fill the aquarium and leave the water for 3 days to a week and then add the fishes. This is because I think I was told it reduces the chlorine content in the water making it safer for the fish.
But if you are referring to tropical fishes as fish that live in the sea. Well sea water fishes cannot live in water because sea water is not their natural habitat. The fresh water does not have in the essential components for the sea water fish to survive in fresh water. Fresh water fish cannot live in the ocean or sea either this is because the pH of the water will kill fresh water fishes. But they are brackish water fishes which can live in water that has more salinity than fresh water, but not as much as seawater.
